Today I’ve to create a temporary solution to backup the Exchange 2010 environment. There’s one simple solution to export all the mailboxes to PST, this is not a prevered solution for a production environment, but it works I’ve used the following powershell commando’s.

1.) New-RoleGroup “Mailbox Import Export Group” -Roles “Mailbox Import Export”
2.) Add-RoleGroupMember “Mailbox Import Export Group” -Member “Administrator”
3.) New-MailboxExportRequest -Mailbox mswi -FilePath \\SRV-EXC01\Z$\Export_PST\mswi.PST

When you want to export all the mailboxes in your Exchange environment, you can use the following powershell command.
foreach ($mbx in (Get-Mailbox)) { New-MailboxExportRequest -Mailbox $mbx -FilePath “\\win2008srv01\c$\PST\$($mbx.Alias).pst” }

Today I had to perform a migration from Microsoft Exchange 2003 to 2010. The new “Move Mailbox” option is replaced with the “Local Move Request“. By default there’s a maximum of two threads at one time…so when you’ve to migrate 1000 users, you’ll have to wait a long time!

You can edit the maximum of two threads within the following file; MSExchangeMailboxReplication.exe.config. This file is located in the installation directory of Microsoft Exchange. In my environment it is D:\Program Files\Microsoft\Exchange Server\V14\Bin

Change the following settings:

• MaxActiveMovesPerTargetMDB = “2″

The default value (as of SP1, version 218.15, at least) seems to be 2. Change the 2 to a 5, or an 8, or whatever you’d like it to be.

• MaxActiveMovesPerSourceMDB – 5, 0, 100
• MaxActiveMovesPerTargetMDB – 5, 0, 100

Save the file, and restart the Microsoft Exchange Mailbox Replication service. Now you can perform 5 move requests at one time!! Cool…
