This morning I received a couple of emails just fine. Then a little later I got the dreaded error saying that mail could not be retrieved because of a logon failure and that the user name or password was bad.

I used my browser to log into the webmail for the exchange server and logged in just fine, so I know my username and password have not been changed by anyone else.

I then searched the internet and found several things to try like deleting the account and recreating, deleting the Keychain Access entry and letting outlook recreate, etc.

I tried everything without success.

Other people are using Windows outlook just fine with the exchange server from the same network.

Finally I called Microsoft Outlook for Mac support and talked to a tech. He connected to my computer and all he did was take the domain off of the username and suddenly it started working. Well, I had already tried that many times, but hey it was working so I was good.

About 5 minutes later it quit working again without any changes. The domain was still just the way the Microsoft tech had set it, so I have to assume it was either a coincidence that it started working for a little bit just when he changed that or him changing that triggered a temporary fix of some other kind. I have tried putting the domain part back in and back out and still not working.

At this point I can't figure out anything that will make it work.

Please help....
