iPhone keeps asking for Outlook password

I had a live.com account that was giving the pop-up (but still loading messages in Mail) so I knew the password was entered correctly. What fixed it for me was re-adding it as an Outlook account in Mail Settings, rather than Microsoft Exchange. Not exactly your issue but possibly related.

Same. Installed 17.1.1 and the requests started. The password is correct as I just hit cancel and my mail updates.

I created an new app password and used it. No change.

As this started with 17.1.1 I have a hard time believing this is an MS issue.

Apple did something ...... again.

I deleted the account - and then added it again, selecting the OUTLOOK option instead of the exchange option. That worked for me.

Here is what I did to solve the problem go to settings open up Mail tap accounts, then tap the account that’s giving you the prompt. It should then ask you for your Microsoft password for that account. Enter your password and that should do it. It appears every time you do an update it logs you out of your Microsoft account so you have to reenter your password.

I really don't think this is an ios 17 issue since it's doing it with ios 16 also. I have the Outlook app on my phone and I receive mail and don't get asked for a password. I think it's probably and issue with the iPhone mail app.

Same here. Someone said to download Edge and sign in from there. Actually, no need to download Edge. Use any browser, sign in to your Outlook.com account and be sure to answer all prompts of “keep me logged in on this device” or similar with yes.

It seems Microsoft have made some changes and stopped ALL protocols from connecting with Outlook.com mailboxes.

Their current workaround suggestion is to browse to Outlook.com on the web and use Webmail ☹

See their acknowledgement of a fault here:

This situation was happening me with my outlook accounts across my MacBook, iMac and iPhone. What fixed it for me was deleting each of the accounts and re adding them. However, on my MacBook and iMac I added the outlook accounts as 'Microsoft Exchange' and on my iPhone I added it as 'Outlook'. Hope this helps some people out.

Same issue here. Its the native IOS mail application.

When entering the password - the mail program redirects to outlook.com to log in, but never saves the credentials in the mail program.

Apple - when will this get fixed?

I don’t believe it’s the iOS. I am currently on 16.6.1 (I haven’t updated in a bit) and I am constantly having to renter my password for outlook. It got to the point where I got locked out and had to change my password, TWICE! Not sure if it’s the app or something else, but I don’t think it’s the iOS, since I’m still running 16.

Here is what I did to solve the problem go to settings open up Mail tap accounts, then tap the account that’s giving you the prompt. It should then ask you for your Microsoft password for that account. Enter your password and that should do it. It appears every time you do an update it logs you out of your Microsoft account so you have to reenter your password.

Well just an update, I did downgrade to ios 7.1 and I try to restore from backup the backup wasn’t compatible with that iOS version so I had to update again to iOS 7.1.1 and when I went to restore the backup from my pc then all the backups were gone, this iOS 7.1.1 is a nightmare, thanks to Apple I lost all my pictures and all my backups

I think it's more a Microsoft problem than a Mac one. I have the same problem, but only with my two Microsoft email accounts. Been going on, off and on, for years, but only with the Outlook/Microsoft accounts. No such problem with my Mac email or Gmail or Yahoo accounts. (Yeah, I have way too many email accounts!)

I do not believe this is an iPhone / iOS issue. I did not upgrade to version 17.3 but the day it was release, and Apple's backend was changed, this message started appearing ..... AGAIN.

This scenario has repeated for each of the 17 releases, regardless of what you use on your i'ish device.

Apple has to fix. Potentially, as one user suggested, an update to your device app might fix. I know I'm certainly getting tired of this. I installed the Outlook mail app to use when I cannot count on one of the largest, if not the largest, tech companies in the world to deliver a functioning mail app.

Same here on an iPhone 15 pro max

this started to happen after upgrade to 17.1.1 as well.

I use Microsoft Authenticator and even as I can workaround it, makes me kind of angry Apple doesn’t test properly their releases.

They also break the Mickey watch face, and today was finally fixed with another upgrade
