Inbox items moving to deleted folder and recover deleted items
We have a few users who are members of a shared mailbox. The users reported that the shared mailbox is moving items from their inbox to the deleted folder. Sometimes the items are soft deleted and go straight to the “recover items recently removed from this folder”. I ran a mailbox audit and it states a few users are either moving them to the deleted folder, soft deleting or hard deleting them. One user in particular shows up a lot. The users are adamant they are not doing the deleting. I’ve across this issue on a few different sites but none have a solution.
I have done the following:
- checked rules and hidden rules in powershell for the shared mailbox and member mailboxes.
- disabled cached exchange mode (found this online)
- disabled download shared folders (also found online)
- disabled auto mapping and manually added the mailbox back
- checked for any patterns in senders
- had the users profiles recreated in the control panel
- checked to see if the emails were tagged as “Ignore”
-created a ticket with Microsoft but they have been no help
Any and all help is greatly appreciated.
