Cause



CAUSE 1

This issue may occur if the CAS resolves to IPv6 when attempting to ping localhost.

      To confirm: Run the following command on the Exchange CAS:  ping localhost 

      Check if it returns an IPv6 value e.g :: 1

CAUSE 2

This issue may also occur if the mailbox being restored to has expired.
     To confirm: Run the restore job with EWS debugging enabled.

     The EWS debug log will show the following error:

      "impersonation principal name is invalid"


Solution



SOLUTION FOR CAUSE 1 

1) Open the hosts file located at %SystemRoot%\system32\drivers\etc\ by using an editor such as Notepad.

2) Add the following lines into the file:
    actual IPv4 address     hostname of the computer
    actual IPv4 address     FQDN of the computer
    actual IPv4 address     localhost

    For eg:
    10.0.100.11     exchange
    10.0.100.11     exchange.domain.local
    10.0.100.11     localhost

3. Save the changes made to the file and restart the Backup Exec services on the Exchange CAS server.

    Run the restore again.

If it still fails, run it with the "When restoring individual mail messages and folders, restore over existing messages and folders" option enabled under the Microsoft Exchange tab in the restore job properties.  

SOLUTION FOR CAUSE 2

 Re-enable the mailbox.
