Update: After contacting Veeam support they attended me that there is a private fix voor version 912.
- stop all jobs
- stop “Veeam Backup for Microsoft Office 365 Service”
- replace Veeam.Ews with the DLL from the archive https://storage.veeam.com/Fix_113114_fbcf2c440c.zip in C:\Program Files\Veeam\Backup365 (don’t forget to back up the original DLL)
- Start “Veeam Backup for Microsoft office 365 Service”
- retry the job
As you can see the problem is solved and I’m able to backup Office 365 again!
People (including me :-)) are reporting problems using Veeam Backup for Microsoft Office 365. It seems that Microsoft made some kind of change on their back-end. At this time Veeam reports that they are looking into the problem..
I’m running Version 126.96.36.1992…. a newer version isn’t available on the general download site. So upgrading the Veeam software isn’t the solution for now.
Don’t seem to be (Windows) update related. Before and after updating my test server I receive the same error. 🙁
When there is a solution I shall mention this in this blogpost.
