User receiving hundreds of blank emails everyday in his deleted items folder
I have a client and one of the users deleted mailbox is constantly being flooded with blank email (no sender, no body, no header) everyday. I have checked mailflow and they do not show up in the logs...
If there are no traces of these messages in the message trace logs, it means they are being generated by the client used, or perhaps some mobile app using the mailbox. One way to get more information would be to enable auditing (owner events included) and go over the audit logs. Or simply remove the mailbox from any apps/devices and test it by only using OWA for a day or two.
