Hi guys, I am experiencing an issue at the moment where a single 365 mailbox (mail enabled team) is getting stuck on ‘Processing Mailbox’

All other Mailboxes are backing up just fine, and the storage on the mailbox is extremely minimal, so it is extremely unlikely that it’s a timing issue. I have increased the backup window and the amount of parallel runs, which hasn’t helped.

Where can I start to look at what’s causing this to fail? Any other suggestions are appreciated.

Edit: I found an error saying this is a possible Teams chat sync problem, will report back if I find a fix
