Outlook 2016 doesn't accept password or app password

I do see the same on Samsung Email for Android. The notable piece is when you choose Exchange as the account type and then type your email address, the "password" field disappears and the modern auth process happens.

I'd been looking into third-party email apps which support EAS, but they all seem to want to connect to your Android client using SMTP/IMAP and then (presumably) their own servers utilise EAS to connect to Microsoft.

I noticed the required permissions when authorising this access (or not!) are different between Samsung Email and the other third-party email apps too.

PS. Please keep us updated on your outstanding ticket with Google :)

I verified now that EAS is working like a charm on Android also for consumer accounts (outlook.com paid or free) authenticated via Oauth (aka "modern authentication") - if I use for example the app "Samsung Email". The integeration with calendar and contacts apps is also working as expected.

So the problem is isolated to the Oauth implementation of the Gmail App. I contacted google via in-app-help and as a result, a support ticket was opened. I am curious whether I get an answer from a human who understands the problem ;-)

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!

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.
