Good Afternoon Experts.
I'd like some help with the following
We use Office 365 with Outlook 2013 clients
If User 1 send an email to User 2 internally it received
User 2 checks the email and send it on to an external email address and BCC's User 1 into the message
The email is received by the external address but not by User 1
This happens intermittently
How can we check where the problem is, is there a way we can track it or monitor the email
Thanks in Advance
