During GLR, if you encounter the error "backup browse result is empty" and you created the AvamarBackupUser manually because the creation tool did not work, you might have run into the problem of the MAPI for the AvamarBackupUser not having been updated.
To fix this follow these steps:
- On the exchange server where the AvamarBackupUser mailbox is located, open a powershell and type the following command: get-mailboxdatabase "mailbox or username" | fl (in this case the user name is AvamarBackupUser)
- Find and copy the legacy DN name
- Create a file called 'avmapi.cmd' in the var folder of the Avamar client install directory (usually c:\program files\avs\var)
- Paste this in that file '--legacy_exch_dn="LEGACY DN NAME"' without the single quotes
- Save file
Now if MAPI was the issue the GLR should work without any errors.
More about the systems I was using:
- Avamar 7.0.1-61
- Exchange 2010 SP3 on Server 2008 R2
- No DAG
