Apple Mail on iOS15 / Outlook.com MFA Application pwd

After updating to iOS 15 my iPhone keeps making me enter the passwords for my outlook.com and hotmail.com email addresses as well. I enter it and it’s good for a few hours then it asks for it again. It’s super annoying every time I open mail or calendar or settings to have several pop up windows immediately pop up asking for the passwords to each of my Microsoft accounts.

Hi sebastien156,

We understand that you're being prompted to enter the password for your Outlook account in the Mail app, and we'd like to help however we can.

You mentioned that the issue is only happening with a specific Outlook account; just to confirm, does the error appear after you attempt to do something specific in Mail with that account? For example, does it appear after attempting to send an email?

If you're unable to send email, please check out this link for some helpful information: If you can’t send email on your iPhone, iPad, or iPod touch

"If Mail asks you to enter a password for your email account, make sure that your password is correct. To check your email address and password, sign in to your email provider's website.

If you still get a user name or password error, contact your email provider or system administrator."

Take care!

I MAY have found the issue. It has been almost 24 hours since I changed it and I haven’t received the pop up telling me that my Exchange password is incorrect. Go to iCloud.com in Safari and check your time zone setting. Mine was set to Pacific which is INCORRECT and must have gotten changed during the iOS 15 update. I set it to the correct Eastern time zone and no pop up so far in the last 22 hours. It’s worth a try and needs to be corrected anyway if it is wrong like mine was. See screenshot.

I am having the same issue but with a different type of account. My setup is for a Google work email account. Due to MFA, I’m forced to use an app password for iPhone setup. The configuration has always been to set it up as an Outlook account and use the created app password. This has worked for a number of years, but after I purchased a new iPhone 13 Pro and upgraded to iOS 15 I am asked for that app password every day. Putting in the correct app password will work, but there is no reason why I should have to keep doing this. It must be a bug. My other email accounts are fine.

Exactly the same issue here using iPhone 13 Pro, iOS 15, working fine with corporate sharepoint but ASKING everyday with private Outlook.com account, I have generate a new App Password everytime. Very annoying!

i have the same problem using apples mail app. every day i have to reenter my password, more often than not, it must be entered multiple times a day. It does not matter if i enter it in the pop prompt or in the mail setting, nothing seems to keep the password saved. Very frustrating.

I have the same problem since upgrading to IOS 15; on only 1 of my email accounts - mocrosoft 365 - my gmail account is unaffected. It will invariably request the password at least once a day, anything up to 4 times a day. Is this is a bug and is there a fix?

+2 instances.

Since upgrade to iOS 15 myself and another in the same org both have started getting prompted for password periodically. password is KNOWN correct. Submitting the password pacified the app for a while then it comes back a while later.

Both of us are on O365 and 3rd party MFA. The “Outlook on iOS“ app does not have the issue, but when opening the iOS Contacts or Mail app, we get prompted for the password.

I reiterate: the password works fine. We have followed the steps in the article below and it only temporarily works around the issue. It doesn’t fix it. It’s basically the same result as entering the password again. It works for a little while then prompts later in the day.

Deleting the account, rebooting, and setting up the account from scratch does NOT solve the problem. I was prompted for my password a couple of hours later.

This bug is preventing me from getting prompted for new emails. I'm missing important emails. Please fix this!

Same issue for me. Since upgrading to iOS 15 on my iPhone 12 Pro, all of my work Microsoft Exchange accounts keep prompting me for my password stating "Password incorrect: Enter the password for the Exchange account". I enter it and a few hours later it prompts me again and it occurs in Mail, Contacts, Calendar, anywhere that it uses these accounts. The issue does not exist for my Microsoft 365, Hotmail, Outlook, Yahoo or Gmail email addresses.

APPLE HELP!

We all have the same problem. It has nothing to do with email provider or the system administrator. It is IOS 15.

The password is requested at least once (if not twice) a day. Prior to this update, it never happened.

I have the same issue. I upgraded to an iphone 13, installed IOS 15 and then 15.1 on the phone. Email was working fine on the older XR running IOS 14. But now, with two Microsoft accounts - one is O365, one is Outlook, I can get into neither. I keep getting asked to sign in on both, and when I do, the reply from Microsoft is the password is incorrect. I have to believe that Apple is 1) not sending the correct password to Microsoft (because this password works on other devices) and 2) if you look in IOS under passwords, nothing is being stored there. This is very puzzling, so I suspect something is wrong with the password facilities in IOS 15. I do not believe this is a Microsoft problem, as others have suggested. There is a bug in IOS 15.1. Shame on me for installing it. I rely on this working through the day, so Apple needs to address this.

The issue is also with a regular MS Exchange account using the username and password authentication. Not only when you use MFA (multi-factor authentication).

Mail app keeps asking for the password practically on a daily basis.

Till upgrade to iOS 15, all worked fine before.

I have also had the same issue as described in this thread. The login information is correct. I can send/receive emails. I just get prompted multiple times a day on both my iPhone (13 Pro Max) and my iPad Pro. This happened right away with my upgrade to iOS 15 and did not ever happen with iOS 14.

I'm having the same problem with iOS15 on iPad and iPhone. Once a day asks for password to Exchange Server account. Never did this before. I just changed the account to be the default so I'll see if that helps. I've deleted the account on both devices. That did not work. I'm assuming this is a problem with iOS15. We'll see if Apple cares enough to fix it.
