The WordPress.com stats helper monkeys prepared a 2012 annual report for this blog.
Here’s an excerpt:
600 people reached the top of Mt. Everest in 2012. This blog got about 3,300 views in 2012. If every person who reached the top of Mt. Everest viewed this blog, it would have taken 6 years to get that many views.
Brief
In Our Scenarios we had 10 Mailbox Server, 5 in each site & 2 Public Folder Server one in each site. We had two witnesses Server, the primary was set in DC1 and the alternate was set in DC2, so our primary Site was DC1.
This article is based on When we have Datacenter Activation Coordination Protocol is Enabled (DACP).
Step1. Ensuring that Primary DC Outage has been Declared
Ping Mailbox Server
Ping HUB Server
Ping CAS Server
Step2. Stopping the DAG from the Secondary DC for Primary DC Mailbox Server
Note:
Stop-DatabaseAvailAbilityGroup –identity DAG1 -Mailboxserver EXM01.contoso.com -configurationonly
Stop-DatabaseAvailAbilityGroup –identity DAG1 -Mailboxserver EXM02.contoso.com -configurationonly
Stop-DatabaseAvailAbilityGroup –identity DAG1 -Mailboxserver EXM03.contoso.com -configurationonly
Stop-DatabaseAvailAbilityGroup –identity DAG1 -Mailboxserver EXM04.contoso.com -configurationonly
Stop-DatabaseAvailAbilityGroup –identity DAG1 -Mailboxserver EXM05.contoso.com –configurationonly
Step3. Stopping the Cluster Service on every DAG-Member of the secondary data-center
Note:
You might see sometime it will result that Cluster Service is already stopped, but no, check using the Services Console, Ensure Cluster Service is in stopped state.
Net stop clussvc
Step4. Reactivate the mailbox-servers in the standby data
Restore-databaseavailabilitygroup –identity DAG1
Note:
Most of the time you will see database will start mounting after executing this command successfully, and also this will start the cluster service on all the DAG members in the secondary DC. If this happens so then skip the step 5, if cluster service has not started perform the step.
Step5. Starting the Cluster Service on every DAG-Member of the secondary data-center
Net start clussvc
or
Open the services console and choose the Cluster Service and start it.
Step6. All the DB should be mounted to the respective Secondary DAG members
Note:
All the DB should be switched to the respective DAG member successfully. If mailbox-databases don’t switch automatically run the script to move databases to passive
Resume-MailboxDatabaseCopy ‘DATABASENAME\SERVERNAME’
or
Mount-Database -Identity ExchangeServerFQDN\DatabaseName
Step7. Check the Status of the DB
Check the DB Copy Status and Ensure they all are healthy. In My Case I had DB Created with Standard Name DB1 to DB72, So I used the below PowerShell to check the copy of all in one shot.
Get-MailboxDatabaseCopyStatus -Identity DB* | select name, status, SelectcontentIndexState | sort Status | ft –auto
Note:
Mount the databases if not done automatically.
Step8. Move OAB Generation to to Secondary Site Public Folder Server
Move-OfflineAddressBook -Identity “Offline Address Book” -Server EXP11
Step9. Do the Final check for Functionalities i.e.
Note:
While accessing the Public Folder using Outlook you might see the outlook hanging but that’s ok, you can ignore it as once the connection get thru with new Public Folder Server, you won’t find the slowness.
Step9. Primary DC Switchback Steps
Note:
You got to know that the Network Connectivity has been resumed to the primary DC.
Also ensure that you got the final instruction that to proceed with Primary Datacenter Restore for exchange.
Ping Primary Mailbox Server
Ping Primary HUB Server
Ping Primary CAS Server
Step10. Ensure Cluster service has been started on Primary Datacenter Server, if not start it
Note:
You will see that Cluster Service is in Disabled state on all the Primary Datacenter in most cases the cluster service won’t start
First enable the service by going to services.msc console and then start it
Or
Net start clussvc
If you are getting the error while starting the Cluster Service, then we need to perform cleanup by running the below command.
Cluster Node EXM01.contoso.com /forcecleanup
Cluster Node EXM02.contoso.com /forcecleanup
Cluster Node EXM03.contoso.com /forcecleanup
Cluster Node EXM04.contoso.com /forcecleanup
Cluster Node EXM05.contoso.com /forcecleanup
Step11. Start the DAG for all the Failed Server
Start-DatabaseAvailabilityGroup -MailboxServer EXM01.contoso.com
Start-DatabaseAvailabilityGroup -MailboxServer EXM02.contoso.com
Start-DatabaseAvailabilityGroup -MailboxServer EXM03.contoso.com
Start-DatabaseAvailabilityGroup -MailboxServer EXM04.contoso.com
Start-DatabaseAvailabilityGroup -MailboxServer EXM05.contoso.com
Step12. Then run the below command from any of the Exchange server
Set-DatabaseAvailabilityGroup –Identity DAG1
Step13. Move the OAB Generation server back to the EXP01 as it was earlier
Move-OfflineAddressBook -Identity “Offline Address Book” -Server EXP01
Step14. Redistribute the Mailbox Database copy across the Primary and Secondary DC
Note:
Ensure all the DBs are mounted and second copies are in health state.
Ensure all the nodes are up and showing good in the Failover Cluster Manager
In My Case I used mine one. You Can use your Own Script to Distribute The DB
Step15. Check all the functionalities
Cheers,
One of the Crucial part before executing any project is Planning, Which is really hard when it comes to Designing a Solution for a kind of Quite Complex Scenarios.
I was going thru few articles but cant find the detailed one, but finally i referred one book Exchange 2010 Best Practices written by Siegfried Jagott & Joel Stidley
It gives you the complete picture about your Exchange 2010 Project Planning, This is completely based on MOF as well as this also talks about live experience.
As per the Microsoft Operation Framework there is four layers Called “Plan, Deliver, Operate and the operation layer called Manage.
This Exchange Project Plan has touched the each layer of Microsoft Framework, Which talks what are do we need to do when as this is important to know about each of this and what we should talk about.
Plan
In this we are mostly going to ask question with client or gather information in the first meeting.
Business Question
Technical Question
Deliver
MOF includes five main steps in this phase: Envision, Project Planning,
Build, Stabilize, and Deploy. But as per real experience this has stretch with four more steps.
Envision
Project Planning
Build/Stabilize
Deploy
Step 1: Envision:
Step 2.Assess :
Step 3: Evaluate the new solution(s):
Step 4: Build a proof of concept:
Verifying functionality is critical in the test environment.
This testing allows time to verify assumptions, verify
functionality, and create a detailed and accurate
deployment design. This is also a good time to learn
more about the product. To prepare for this work, gather
all of the software, hardware, and configuration guides that
are being considered for use in the design.
Deploy an isolated test environment that is as close as
possible to the expected production environment and
allows testing to be completed. Testing in this phase should
include potential migration scenarios.
Perform the test scenarios and note the detailed results. Be
sure to note any changes to the test scenarios
because of new or changed features.
After the testing is completed, the issues and potential
changes should be reviewed. The reasons for any
unexpected results should also be captured. For instance,
did the test fail because a feature or function didn’t work as
expected, or were there limits reached?
The review should categorize each issue’s criticality and
then each issue should be addressed by changing the
design, opening support cases with the appropriate
vendors, or adjusting the current process to accommodate
the new functionality. Any user behavioral changes should
be documented and later clearly communicated to the
affected users.
Step 5: Create a Design
Step 6: Develop the deployment and obtain buyoff.
Step 7: Implement a pilot. Begin pilot, adjust the plan, and complete deployment.
Step 8: Deploy:
Step 9: Post-implementation review:
At Last the its Manage where you can take care for these Points.
Manage
Governance, Risk, and Compliance
Change and Configuration Management
Process Improvement and Management

Exchange 2013 has been announced
http://www.microsoft.com/exchange/en-us/exchange-preview.aspx
Exchange 2013 Preview Can be Downloaded From here
http://technet.microsoft.com/en-US/evalcenter/hh973395.aspx?wt.mc_id=TEC_116_1_33
Stay Tuned, I am in the preparation of Posting More on Exchange 2013.
As you can see here DB030 shows as Failed for DAG Member EXM15, to get this fixed we have to reseed the DB.
As you can see below
Note: The duration of the seeding process will depend on the size of the database and the speed of the network. When the update has completed it will automatically resume replication for the database copy.
Just in case if you want the replication to resume it manually use the below command.

Architecture: Blackberry Enterprises Solution
The Blackberry Enterprises Solution has been got used using this component. This is the standard architecture of data flow between the Blackberry devices to Messaging server.
Component Description
BlackBerry device: The BlackBerry device provides Access to email messages, calendar, Contacts, Enterprises Global Address Lookup
Wireless network: The wireless network routes the data to and from the BlackBerry devices to the Internet through the BlackBerry Infrastructure.
BlackBerry Infrastructure: The BlackBerry Infrastructure is designed to provide a highly secure and reliable connection to wireless networks operated by
many service providers around the world.
Internet: The internet component is not mentioned here, however this is very much require to transport the data Internet transports data between the wireless network and the firewall.
Firewall: The BlackBerry Enterprise Server maintains an outbound-initiated, bidirectional connection through port 3101 on the firewall and over the Internet to the BlackBerry Infrastructure.
Introducing the BlackBerry Enterprise Solution
BlackBerry Enterprise Server:
The BlackBerry Enterprise Server is installed on a computer behind the organization’s firewall. The BlackBerry Enterprise Server is designed to
• Manage the wireless transfer of data to and from the BlackBerry devices
• Encrypt all data that flows to and from the BlackBerry devices
• Allow highly secure push delivery of content to the BlackBerry devices
Messaging server:
The BlackBerry Enterprise Server integrates with the following messaging servers to provide wireless delivery of email messages and organizer data
• Microsoft Exchange
• IBM Lotus Domino
• Novell GroupWise
Instant messaging server:
The BlackBerry Enterprise Server integrates with the following types of instant messaging servers to allow highly secure, wireless delivery of instant messages and data:
• Microsoft Office Communications Server
• Microsoft Office Live Communications Server
• IBM Lotus Sametime
• Novell GroupWise Messenger
Application or content servers:
The organization’s application servers or content servers provide push applications and intranet content that the BlackBerry Enterprise Server makes available to the BlackBerry Devices.
Email flow for the BlackBerry Internet Service
This below design we have outlined for the email flow when a blackberry device sends emails to another Blackberry device using Blackberry internet service.
1. An email message is sent from a BlackBerry smartphone. The email message is compressed so that it is in CMIME format and sent to the wireless network.
2. The wireless network delivers the email message to the BlackBerry Infrastructure.
3. The BlackBerry Infrastructure uses the UID field in the [CMIME] service book to deliver the email message to the appropriate BlackBerry Internet Service server.
4. The BlackBerry Internet Service converts the email message to standard MIME format and sends the email message to the Internet. The email message is sent through the Internet using SMTP to the recipient’s messaging server.
5. Then the messages reaches to the recipient users, Then once the recipient replies to that email, the data flow happens as mentioned below.
6. An email message is sent to the BlackBerry smartphone user from an email application on the computer. The email message is delivered through the Internet to the BlackBerry Internet Service.
7. The email message is compressed by the BlackBerry Internet Service so that it is in CMIME format and sent to the BlackBerry Infrastructure.
8. The BlackBerry Infrastructure sends the email message to the wireless network using the current assigned PIN.
9. The email message travels over the wireless network to the BlackBerry smartphone which decompresses the email message.
Email flow for the BlackBerry Professional
The below outline shows – the email data flow in the infrastructure of Blackberry Professional & Messaging server.
1. BlackBerry smartphone User A creates an email message and Sends it. The email message is compressed, encrypted, and sent to the wireless network.
2. The wireless network sends the email message to the Internet through the BlackBerry Infrastructure.
3. The email message reaches the firewall, where it passes through an outbound-initiated, two-way connection to the BlackBerry Professional Software.
4. The BlackBerry Professional Software decrypts the email message, decompresses it, and places it in BlackBerry smartphone User A’s outbox.
5. The messaging server forwards the email message to the recipient in the organization.
6. The BlackBerry Professional Software monitors User B’s mailbox and retrieves the new email message. The new email message is applied against global and personal email message filters. If the email message is being sent to BlackBerry smartphone User B’s BlackBerry smartphone, the BlackBerry Professional Software compresses and encrypts the first 2 KB of the email message and queues it for delivery.
7. The email message is sent by the BlackBerry Professional Software through an outbound-initiated, two-way connection on the firewall to the Internet.
8. The email message is sent through the Internet to the organization’s firewall.
9. The email message arrives at User B’s mailbox.
Email Message flow for the BlackBerry Enterprise Solution
Email messages sent to and from BlackBerry smartphones the following scenario outlines the email message flow when an email message is sent by a BlackBerry smartphone user in one organization
(BlackBerry smartphone User A) and received by a BlackBerry smartphone user in another organization (BlackBerry smartphone User B) through the BlackBerry Enterprise Solution
1. BlackBerry smartphone User A creates an email message and sends it. The email message is compressed, encrypted, and sent to the wireless network.
2. The wireless network sends the email message to the Internet through the BlackBerry Infrastructure.
3. The email message reaches the firewall where it passes through an outbound-initiated, two-way connection to the BlackBerry Enterprise Server.
4. The BlackBerry Enterprise Server decrypts the email message, decompresses it, and places it in BlackBerry smartphone User A’s outbox.
5. The messaging server sends the email message as SMTP traffic through the firewall using the port designated for email messages.
6. The email message travels across the Internet as SMTP traffic and arrives at BlackBerry smartphone User B’s firewall.
7. The firewall allows the email message to pass through to the messaging server, where it is placed in BlackBerry smartphone User B’s mailbox.
8. The BlackBerry Enterprise Server monitors BlackBerry smartphone User B’s mailbox and retrieves the new email message. The new email message is applied against global and personal email message filters. If none of the filters apply to the email message, the BlackBerry Enterprise Server prepares to deliver it to BlackBerry smartphone User B’s BlackBerry smartphone. The BlackBerry Enterprise Server compresses and encrypts the first 2 KB of the email message and queues it for delivery.
9. The BlackBerry Enterprise Server sends the email message through an outbound-initiated, two-way connection on the firewall to the BlackBerry Infrastructure.
10. The BlackBerry Infrastructure sends the email message to the wireless network.
11. The wireless network receives the email message and forwards it to BlackBerry smartphone User B’s BlackBerry smartphone.
12. BlackBerry smartphone User B’s BlackBerry smartphone receives, decrypts, and decompresses the email message. BlackBerry smartphone User B’s BlackBerry smartphone also sends a confirmation notification to the BlackBerry Enterprise Server to indicate that the email message has been received.
Email sent to and from BlackBerry smartphones in the same ORG
The following scenario outlines the email message flow when an email message is created and received by BlackBerry smartphone users (BlackBerry smartphone User A and BlackBerry smartphone User B) in
the same organization through the BlackBerry Enterprise Solution.
1. BlackBerry smartphone User A creates an email message and sends it. The email message is compressed, encrypted, and sent to the wireless network.
2. The wireless network sends the email message to the Internet through the BlackBerry Infrastructure.
3. The email message reaches the firewall, where it passes through an outbound-initiated, two-way connection to the BlackBerry Enterprise Server.
4. The BlackBerry Enterprise Server decrypts the email message, decompresses it, and places it in BlackBerry smartphone User A’s outbox.
5. The messaging server forwards the email message to the recipient in the organization.
6. The BlackBerry Enterprise Server monitors BlackBerry smartphone User B’s mailbox and retrieves the new email message. The BlackBerry Enterprise Server checks the global and personal email message filters. If none of the filters apply to the email message, the BlackBerry Enterprise Server prepares to deliver it to User B’s BlackBerry smartphone. The BlackBerry Enterprise Server compresses and encrypts the first 2 KB of the email message and queues it for delivery.
7. The BlackBerry Enterprise Server sends the email message through an outbound-initiated, two-way connection on the firewall to the BlackBerry Infrastructure.
8. The BlackBerry Infrastructure sends the email message to the wireless network.
9. The wireless network receives the email message and forwards it to BlackBerry smartphone User B’s BlackBerry smartphone.
10. BlackBerry smartphone User B’s BlackBerry smartphone receives, decrypts, and decompresses the email message. BlackBerry smartphone User B’s BlackBerry smartphone also sends a confirmation notification to the BlackBerry Enterprise Server to indicate that the email message has been received.
Note: To made this Blackberry Flow Design – I had prepard the VISIO Stencils, using that i made it. I will be posting those stencial & the softcopy of the VISIO Diagram, which i have prepared.
Scenarios :
While working daily on ticket, You have lots of stuff to work on, in Between you got a mail from Monitoring Team saying that, Team the disk space got full for log drive on one of the BES servers. On top of it your Lead asks – cant you guys put one script to do the automation here.
So finally here is that automation, which is gonna to delete old date logs automatically (Its all up to you for how many days you wanted to retain)
Solution:
=======================================
Examples:
This command will move logs older than 7 days from the folder “C:\Scripts\logs” where folder name value only contains numbers like “21112010″.
cscript //NoLogo c:\scripts\deleteBESLogFolders.vbs “C:\Scripts\logs” 7 move>> c:\scripts\BESLOg_Folder_Delete.log
This command will delete logs older than 7 days from the folder “C:\Scripts\logs” where folder name value only contains numbers like “21112010″.
cscript //NoLogo c:\scripts\deleteBESLogFolders.vbs “C:\Scripts\logs” 7 delete>> c:\scripts\BESLOg_Folder_Delete.log

Issues :
one Day we came across with case, where a high profile users were loose lots of contacts & after checking with them we found “User’s Blackberry Device were not able to sync the Contact field (Mobile 2) from the Blackberry to MS Outlook.
Solution
There has no solution made so far, User has to save all the mobile 2 option to diffrent category, i.e Business No, Home No etc.
Note : Even the same issues happens with Nokia as well, why becasue in outlook we dont have the field for Mobile 2.
Problem : User is not able to attach the file from the media card using emails on model 9800 Blackberry Torch Device.
“we found user device was content protection enabled, which usually organization use to protect the device, Specially this issues we came across to 9800 models only.
Workround : Just disabled the mdeia card encryption by going to the Media card properties.
Solution : This has been fixed in 6.0.0.287 (Bundle 870) and above. AT&T is not yet released the device software version 6.0.287 and users are required wait until the update is available.
