Message: '''Login to server outlook.office365.com with username [email protected]''' (my work email account set up thru GoDaddy) '''failed'''. This is not my primary method for using my work email (Gmail's webmail interface is and, yes, still works fine). But every once in a while, I want to use the features of TBird that aren't possible with Gmail. So, I tried running TBird last weekend and got that message. So, first I tried signing in thru GoDaddy (O365 webmail) and used my existing password, and of course it worked fine. I then tried deleting the TBird account and adding it as new. TBird recognizes O365 accounts and I used those settings but, again, the password was rejected. So I went semi-nuclear and uninstalled TBird then reinstalled it. NO DIFFERENCE. WHY is TBird rejecting my valid password - ESPECIALLY when it was working before? Please pardon the raised voice all caps here and there - I'm really frustrated and don't understand what broke or how it broke and I can't fix it. HELP!
