One of our mailboxes is generating duplicate queue items in its queue. The other mailboxes/queues function without problems.
When I check the duplicate queue items in detail, I only see a difference in the Created/Modified by (delegate) fields:
The cause of the problem could be that someone gave the mailbox Dynamics access rights a little while ago. But that has been solved already.
Besides that the configuration of the environment has not been changed (MS updates maybe)...
What I checked so far:
- No workflows on queue items of queues
- No routing rules
- No mailbox sync errors
- Configuration of the mailbox and the queue are the same for other queues in the same environment (not experiencing this problem)
Unfortunately this is a production queue, so I cannot recreate it.
It is a Dynamics online (Version 1710 (9.1.0.15051) ) with Exchange online environment.
Anyone has a suggestion?
Thanks a lot!
