After releasing Exchange Server Service Pack 1 (SP1) Microsoft added new functionality called Export-Mailbox cmdlet for Exchange Management Shell.
The Export-Mailbox cmdlet exports all message types, including messages, calendar items, contacts, distribution lists, journal entries, tasks, notes, and documents. However, the Export-Mailbox cmdlet does not export rules.
To export data from a .pst file, you must run the Export-Mailbox cmdlet from a 32-bit computer that has the 32-bit version of the Exchange management tools and Outlook 2003 Service Pack 2 (SP2) or Outlook 2007 installed.
Well all prerequisites were in place; I opened the Exchange Management Shell and run the following command line:
[PS] C:\Documents and Settings\admin>Export-Mailbox -identity user1 -PSTFolderPath c:\user1.pst
Confirm
Are you sure you want to perform this action?
Exporting mailbox content from the mailbox ‘Gaag, van der Rob’ into .pst file ‘c:\gaagr.pst’. This operation may take a long time to
complete.

Export-Mailbox : Error was found for User1 (user1(at)networknet.nl) because: Error occurred in the step: Moving messages. Failed to copy messages to the destination mailbox store with error:

The export failed. After reading some posts on Google I found the solution myself. I tried to export my own mailbox which worked fine so the problem has to be within the permissions set. To get full access run the Add-MailboxPermissions cmdlet.
Add-MailboxPermission -identity user1 -Accessrights FULLACCESS -User admin
Export-Mailbox -identity user1 -PSTFolderPath c:\user1.pst
With these steps I can develop a procedure to backup mailboxes when they are removed from the system.
