Apple Mail on iOS15 / Outlook.com MFA Application pwd

Tried deleting and reinstalling exchange email and still have the issue.

also having map issues where it just doesn’t know where phone is until I turn off phone and restart.

come on Apple fix this stuff!!

After 24 hours, iOS 15.1 update appears to have fixed this issue for me as well. Accessing via several devices and various exchange based email servers including gsuite accounts using app passwords all of which previously prompted at least daily to re-enter password.

Yes, after the iOS/iPadOS 15.1 update, the problem seems to have been patched in the mail application. It only prompted once after the update, but never again all day today. Looks like we were able to bring enough attention to the problem.

On my iphone 8 the automatic reply was stuck in “loading” mode. Go into Setting> mail> accounts> , then open the mail account that you keep getting a request to enter your pw for. On my phone the automatic reply on the bottom of the screen was stuck in “loading”. Enter your pw again and then hit the > to open it, i turned the automatic reply on and then off again, cos I wanted it off, and now the requests for the pw have stopped. I went on to my iPad to do the same thing, but when I went got to the last steps the two synced. Hope this works for you.

I am having this exact issue after updating to iOS 15.0.2. I have tried resetting the phone, deleting and reinstalling all mail apps, VPN is turned off, time zone is correct, etc. This is happening on my Office 365 work account. I ONLY use Outlook App for iPhone for this mail account, so using the Outlook App rather than native Apple Mail app is not a fix.

Agree iOS 15.1 DO NOT fix the issue. a bad reaction was to remove the Microsoft account and now I cannot connect back iOS mail and Outlook hence I cannot see the calendar with my other accounts.

The mail @ and pwd are correct since I can connect via a browser!

I think I found the problem. It’s not the Mailor Outlook apps it’s Contacts, go to Settings - Contacts - Accounts - click each exchange account and you’ll see on top Account not authenticated. Re-enter password should fix the problem

I too had this problem recently after updating to IOS 15.2 on my iPad and iPhone. Both devices had trouble verifying my personal Outlook account from Settings > Mail > Accounts. I have verified that I entered the right password since I could login to my Outlook from browser just fine.

I too have tried deleting, rebooting, and adding the account back (by adding Outlook.com). This did not work at all, as I encountered the same issue (unable to verify my account)

The fix: The only resolution for me to is to add “Exchange” rather than “Outlook.com”. This method worked well and I was able to login, sync my mails, reminders, notes, etc. Give it a try and hopefully it will fix your connection issue.

On an iPad 6th generation, I upgraded to 15.2 on 14 Dec 2021 began to observe the problem on the evening of 15 Dec.

(I have not observed the problem for the same outlook accounts on an iPhone 7 also running ios15.2)

The problem occurred for both outlook accounts in my accounts list.

I was repeatedly prompted for both passwords.

I would re enter the password, but nothing seemed to happen when I hit the submit button.

when I looked at the account, I could see that it was still requesting I re enter the password.

I restarted the iPad and still observed the same behavior.

I deleted one of the outlook accounts but could not add it again. Today, the one remaining outlook account seems fine.

I attempted deleting and re-adding one of the outlook accounts, but cannot re-add the account.

1) I tested my username/password combination by logging in via the outlook.com web interface.

2) I used “add account”, typed in the username and password when prompted, then used the “Submit” button

3) I observed that the process stopped at that point - I was looking at the list of accounts. The new account was not added.

There were no error messages or any other type of message after I used the “submit” button.

I don’t know if this will work for everyone, but for me the problem was because of the Contacts account, and not email.

I went to settings > contacts > accounts and one of them is my work’s email (which uses exchange). I re-entered the password for it and I stopped getting the pop up

I do not sync contacts with outlook.com so it is not enabled. As of 12/16 I am no longer able to use the mail app with an outlook.com personal account configured with MFA. You can setup the account but only get the message: "Account Error" at he bottom of the mail app. Upon clicking details you then get "Cannot get Mail: The connection to the server failed"

Removing MFA is not an option. There is also no method of entering the app password. It should also be noted that using the Outlook mail app works fine.

I should elaborate that it does this for every Microsoft account that is personal. It does not do it for my college or work accounts which are Microsoft 365.

I am facing exactly the same issue. In my case the password works for almost a day and then I need to re-enter it.

Also want to add that this same problematic account seems to work fine for my iPad Mini 5th gen running iPadOS 15.

Same issue here with an exchange email account and iOS 15. My password is correct and I’m the Mail admin. No changes on outside.
