17.3 Mail password issue on Exchange account

I had the identical problem just before I updated to 17.3 and it continued after the update. I was able to work around it by creating a new account using outlook instead of Exchange for mail default and phone has worked fine since. However, I also got requests for Exchange password on my laptop for email. I entered it once as well as checking box to remember credentials. When the message pops up requesting password, I just go into mail and click on the "need password" message and it resolves. It's clumsy but gets around issue. There appears to be an issue with iOS and Microsoft interface causing this on Apple and PC devices.

The same problem here. Definitely a problem since the update to 17.3.

I still have my old iPhone running on 17.2.1 here, which works perfectly. Same problem on my wife's iPhone (17.3).

However, I have not activated 2FA. I use the Apple Mail app and my mailbox is configured as an exchange mailbox.

It is definitely a MICROSOFT problem. Microsoft has said so. It is coincidence that Microsoft’s system broke around the same time as Apple released 17.3; I have seen posts from users who said the problem started BEFORE they updated, and they were hoping the update would fix the problem.

There are other posts in this thread that have links to the Microsoft support threads.

The same thing happens to me on Android, the problem started on January 24, 2024. Apparently it is a Microsoft Exchange Active Sync problem. Using another sync protocol works

Thank you, sn0ck. It is apparently coincidence that Microsoft added required 2 factor authentication about the same time that Apple released the latest update.

There is another option, and that is to use either Passkeys (which both Apple and Microsoft support) or hardware security keys→About Security Keys for Apple ID - Apple Support, which both Apple and Microsoft also support. Both of these options can replace passwords entirely.

Apple is NEVER going to fix it, because it is a Microsoft problem, and Apple doesn’t have access to Microsoft code. And it isn’t since the 17.3 update, it actually started a couple of days before 17.3 was released. Go back and read this thread, and you will find solutions on how to fix a problem introduced by Microsoft.

I have the same annoying problem (both iPad & iPhone) and I don't have a IT department to help me with this!

then you report the issue to Microsoft or look at their help site/forums.

The same problem here. Definitely a problem since the update to 17.3.

APPLE PLEASE FIX THIS. Having the exact same issue on my iPhone. Luckily I have not upgraded my MacBook to the new software yet.

Apple does not read here for feedback or suggestions. You can, however, let them know your thoughts here:

Yes, exactly the same issue. I have an iPhone 13 mini, upgrade IOS to ver 17.3 and have had Exchange password issue since then. Works fine on my laptop. I get the message 'Password Incorrect', Enter the password for the Exchange account 'Exchange'. This appears 2/3 times after I cancel. Tried switching off phone and on again this morning and it was ok for a while but has now reappeared. Entering the correct password doesn't resolve,

The same troubleshooting tips that was given to the OP applies to you too.

This isn’t a Microsoft problem, now either my iPad or my IPhone connects to WiFi saying my password is incorrect. Putting the correct one over and over again doesn’t resolve the issue! Please fix this!

There are no IT folks and this is not a Microsoft issue as with both 17.2 they worked fine.

if you don't want to reach out to Microsoft to troubleshoot then that is up to you.

there is no Apple here in these user to user technical of forums.

Same issue here on 2 iphones and 1 Ipad at my house. One Iphone made the upgrade without issue, but it is a 15 Pro Max so maybe something newer about it vs the iphone 13. Seems like lots of folks with this issue, but no solution

Microsoft support wasn't able to help you with their exchange account? Apple has no clue what your exchange password is.

The error says its connection with server error.

But in iOS 17.2 this error didn't existed, it appeared after iOS update to 17.3

It could be Microsoft error, but most likely Apple changed something about the settings that peopple on 17.2 still have access and 17.3 doesn't

Also whatsapp ilost all contacts for me... so big trouble for my work here.

Never updating again for a long time...
