Outlook 2016 doesn't accept password or app password

Gabriel,

Thanks for your analysis!

I have been beating my head (figuratively) on my keyboard with this issue. I had one hotmail.com account, and one outlook.com account.

I got notice that my hotmail.com account was going away. the hotmail.com account was my "Microsoft Account", so I logically (in my eyes) decided I better make my outlook.com account my "Microsoft Account> Which I did.

Then, to my dismay I realized that my hotmail.com did not entirely go away, just the email portion.

Now, I have the hotmail.com and outlook.com battling over control of my "Microsoft Account". Great fun! I go back and forth with each of them wanting me log into live.com and validate my account. The 2 factor authentication flips back and forth for ownership of my phone number. More fun!

But your statement about hitting "update folder" to get access back to Microsoft Exchange sure worked for me. Its not ideal, but better than what I was dealing with!

Thanks again!

MS is not going to fix this. If this is important to you, I'd suggest you move everything off Microsoft's ecosystem. Honestly, I have had more and more Microsoft issues, spanning from Windows, to Edge, to Office, to Outlook, to Teams...to Skype. MS is rushing to change everything and we, the customers, are their QA. It seems like I am constantly dealing with MS bugs.

Any news on this?

At the moment I have permanently deleted the Microsoft accounts from Outlook 2016 and I only use the latter for a pec email from Aruba which at the moment has no problems. I access Microsoft email via web browser.

It depends on your account and usage pattern. I came back from an overseas business trip 10 days ago and it was prompting me constantly. After a few days, it settled down. However, on my phone, I am still getting prompted left and right, nearly constantly. I have moved most stuff off Microsoft system and working on the final bit of data, so I still have my phone logged into the account via EAS.

I think it saw the sudden change in IP address and region as a clue but it's such an antiquated way of doing things when it captured my device's UUIDs. Google is got this down to a science. Google challenges me when I feel I should be challenged but my usage, location or pattern is so out of norm. Microsoft' approach feels like some 2nd grader wrote the logic.

Now, if you look at Microsoft's strategy of auto-login into every damn app, be it Windows, Edge, Teams, Office.... all without additional password prompts, I don't get this unusual scare and care on EAS.

I must say that things have settled down - still getting the prompts for each account on opening Outlook 2013 but all mail functions are working.

(Unsuccessfully trying not to succumb to nostalgia for this thread.)
