I have a user that receives the following Undeliverable message when using Company Exchange and his Personal POP e-mail account in the same Outlook.
Tried many things, but I can't get it to stop happening.
Here's the rejection e-mail (edited for privacy):
Your message did not reach some or all of the intended recipients.
Subject: (subject here)
Sent: (date here)
The following recipient(s) cannot be reached:
=SMTP:(email address here) on
The recipient has been deleted or has no e-mail address.
The e-mails are all valid. I have verified all the MX records... Am at my rope's end. Can anyone please help?
