I have a very strange problem that happens once in a while with a specific user. So far it's happened a couple of times.
This user has his mailbox configured to forward all emails to an outside address AND leave a copy in the mailbox.
This works 99% of the time, except that a couple of times the user has received the email in his external account, (a personal account) and NOT in his mailbox.
The exchange logs show NO trace of the email ever being sent to that user.
Today I received an email that had this user in the CC field, but he didn't get it in his mailbox.
When searching exchange, I see the email that came to me, but in the recipient field in the logs it only shows my name.
This is very strange and I have no explanation to give this user.
How can this be? How can exchange forward the email, show the CC in my email and not show this mailbox receiving this email?
Thank you so much for any ideas you can have as I am stumped.
