As a workaround you could install the Veeam console on your normal PC and do the restore through this PC - so you do not need Outlook on the Veeam Server but only on your PC
That's true, but I had to have the 64-bit version of Outlook and I'm running 32-bit for the moment. I installed a 64-bit version on the backup server, so it's working fine now.. Just thought that the best thing would be to do this without the need of Outlook.
At this moment you indeed need Outlook installed to be able to restore to a PST. We have had this request before and it is already tracker but not yet possible at this moment
