As of yesterday evening, ExMixedFolders has stopped synching all jobs. We are getting the following error in logs:

Exc1:ForChanges Versions: V2018_01_08 => An internal server error occurred. The operation failed., IdAndSession.MailboxSession: session is not IMailboxSession

Hi,

This seems to be a new bug of Office365. I will try it on my own Office 365 if I will get the same error.

Yes, I got the same error now. But I can't do anything. It's a Microsoft Bug in Office 365. We have to wait until they fix it.

As well I made a ticket from my Office 365 account. Let's see.

Hi,
