Using the New Outlook for Mac for personal email and calendar
Hello,
I will walk through a few steps with you. Some of these are just to help figure out what is wrong, not to fix it right away. So if nothing changes after a step, that is normal. I will keep going until we solve it.
Please send from one of your other email accounts to this problematic account. Let me know if you get a bounceback message - and post the same completely.
I look forward to hearing from you to get the results of the troubleshooting.
