Hi,
Super strange issue here, sometimes UserA's email end up appearing in UserB's junk folder.
UserA does have delegate permissions to UserB's mailbox - but that shouldn't cause this.
UserA is the only person the email is to and UserA also have the email.
There are no forwards on.
There are no rules in place or OoF.
There are no duplicate emails addresses, aliases, GUIDs and it does not happen to all emails. It did it this week for 4 emails in the period of an hour and then has not done it again since (yet, I say yet as this is not the first time).
Looking in the message tracking logs, I can only see the emails from the external sender being delivered in to UserA's mailbox - nothing to UserB's.
This is Exchange 2010 SP3 RU21.
Anti Spam is not enabled.
I have no idea how this is happening. UserA has been with the company for years so this mailbox was definitely upgraded from 2003 version which may have something to do with it - however, I have looked through ADSIedit and can't see anything that would indicate
this behaviour.
I am getting approval to turn on mailbox auditing for these two mailboxes - but that may take a while and once on, the issue could take a while to happen again.
Any ideas what else this could be?
Thanks - James.
