Using New Outlook on Windows for personal email, calendar, and contact management
Eben,
We tried to reply to your email but it got returned (with different reasoning than the other emails). Here is the message we get when we receive return emails from aol, comcast, yahoo, sbcglobal, and gmail plus a few others:
Delivery has failed to these recipients or groups:
(example email) ABCDEFG (******@aol.com)
Your message couldn't be delivered. Despite repeated attempts to contact the recipient's email system it didn't respond.
Contact the recipient by some other means (by phone, for example) and ask them to tell their email admin that it appears that their email system isn't accepting connection requests from your email system. Give them the error details shown below. It's likely that the recipient's email admin is the only one who can fix this problem.
