I am seeing 10-20 hours delay in receiving TFA emails, or not receiving them at all, from @tmcaz.com and delivery failure due to taking over 24 hours for emails from @arizona.edu
How can I get this...
I'm seeing the same problem with mail my spouse is sending to me. Different Exchange server, but the same error message. Most messages don't go through, and the few that do take 20+ hours for a simple message with no attachments.
