Hi,
A customer is running Exchange Online since several months back and after an update late March (currently 11.22.13) some mailboxes type group, started to appear in the backups. This seems to be Teams Group created mailboxes and they are not included in the AD associations for backing up online mailboxes.
So far 23 of these mailboxes has turned up in the customer environment and I’m not sure they are wanted.
I am wondering if this is a feature coming with the support for Teams backups and if this is normal behaviour. If so, how can it be disabled or excluded from the user mailbox backups?
If it’s not normal I suppose a fix will be in place shortly.
/Patrik
