Gmail app keeps asking for Microsoft account credentials - not able to login

Hello Everyone,

We truly appreciate your collaboration and understanding on this matter.

As per checking onto this, there was an issue on the Outlook.com server authentication where emails apps connecting to POP, IMAP, or Exchange connections are being prompted to enter credentials, here the support article for reference: Outlook and other apps are unable to connect to Outlook.com.

If you are still having the same issue, we highly suggest creating an app password for your mail applications. Using app passwords with apps that don't support two-step verification

I hope this information helps!

Two-step enabled, using app password - still having same problem. Not fixed!

Two-step enabled, using app password - still having same problem. Not fixed!

Same here, I had the app password enabled and working, but in the last weeks I have been "kicked out"

Tried to delete and readd and since then I'm not able to get my email address in Gmail app.

A couple of days later it started to give the same issue with another account without the 2 step and the app password

Similar issue but slightly different.

Two different android devices, one much older S2 Tab (Samsung) and a Pixel 7a. Second device didn't have the account on it until I started to troubleshoot.
Exchange\O365 Email account stopped syncing this week on the S2, I have seen the info about that already.
Account is part of a group that bypasses 2FA due to a very specific use case.

Trying to delete \ re-add the account wasn't at first successful earlier this week (possibly due to the MS issue) once it was it can usually send/receive on the first sync and then it won't sync.

Adding the same account to the Pixel has the same behaviour, first sync then nothing.
Both app versions for the Gmail client are the same so I suspect auto-update is on, 2024.01.14.599541078.release
Haven't had a chance to try roll back Gmail client.

More testing adding the Outlook official app on the Pixel and sadly its working perfectly fine so far (only been an hour).
Unsure if this is MS doing things intentionally or a ball drop from Google.

Thanks for looking into this!

I have exactly the same problem, I tried several things without any success.

• Gmail App updated (2024.01.14.599541078)
• using App Password
• using several aliases for the server connection (eas.outlook.com, outlook.live.com, outlook.office365.com, m.hotmail.com, etc.)
• using dns resolved name : ams-efz.ms-acdc.office.com
• using several dns resoved ip adresses
• port 443 or 993
• setting up a complete new outlook.com account, has same problems

In noted this:

• IMAP in gmail app syncs fine (email)
• installed outlook app for Android, syncs fine (email, contacts, calendar)
• all known aliases for the server name are resolving to the same dns name: ams-efz.ms-acdc.office.com
• using ip addresses instead of server name give slightly different error message: There was an error, please try again
• gmail app is only asking for a "server", not "incoming server"
