17.3 Mail password issue on Exchange account

UPDATE, deleted my email account and reinstalled seemed to fix it 12 hours so far.

Since I updated four devices with operating system 17.3. My exchange

account keeps telling me “Password Incorrect Enter the password for the

exchange account “Exchange”.  I have

changed the password once and deleted the Exchange account and created it again

several times. I keep getting the same message and exchange does not work.

Since I can get email through other devices which do not use Exchange, my

password is correct. I have tried advice from Sup_Traste and deleted my

Exchange account and created a Outlook.com account and got what I wanted, Mail,

Calendar, Contacts, Reminders, and Notes. Now I can synchronize my Outlook on

my PC to my iPhone and iPad. I also use Authenticator and it was a seamless transition.

exactly the same problem - since the 17.3 update, my exchange account constantly asks for the password every morning. The only way to stop it is to open the Mail account settings for that account, disable calendar syncing, wait until it’s deleted all the calendar entries, then reenable it, and wait until it’s resynced. Boring, but I can live with it as long as Apple fixes it in the next update (soon)!

Try deleting the Exchange account from your phone and adding it back.

When I entered the correct password on my iPhone, it still gave me the incorrect password message.

Only by changing from Exchange account to corresponding outlook account on my iPhone was I able to get the messages to stop. Then I started getting requests for password on PC and entering correct password there worked.

When you re-added it you didn’t enter the correct password for outgoing mail, or perhaps you believed the text that said it was “optional”. It isn’t optional.

But the problem wasn’t the 17.3.1 update; the actual problem was a change in Microsoft’s authentication policy design a couple of days before the iOS update.

You have a Microsoft email account. Your choice is to follow Microsoft troubleshooting advice or live with the problem forever. Microsoft has publicly said that the problem is on their end, and has provided guidance to fix it. You can either go to Microsoft support or just read thread you posted to, which has all of the information you need that other users got from MS support.

Apple does not have the resources to fix Microsoft’s email server.

Well, then you didn’t read carefully. FIRST: This is not an iOS problem, it is a Microsoft problem. Microsoft changed how authentication works several days before the iOS release. So the answer (which is in this thread multiple times) is to visit Microsoft Support for how to address this issue with Microsoft services.

FYI.. I wrote my previous post above 45 minutes ago. Since then, I turned my iPad completely off for 5 minutes, then turned it back on. The problem seems to be gone, thankfully. Whether it stays that way remains to be seen.

You have come to the right place; the answer is in the thread you just posted to.

It is a Microsoft issue. There are other posts in this thread that have links to the Microsoft support threads, so go and read the previous pages of the thread to get the answer.

Actually, the best answer is by Tech_Addict on Page 2 in this thread→https://discussions.apple.com/thread/255437852?answerId=260116119022&sortBy=oldest_first#260116067022

What you really have is the same problem after Microsoft changed their supported authentication methods, a few days before Apple released iOS 17.3. If you go back and read the thread you posted to you will see suggestions from people who resolved the problem using Microsoft’s support center.

You saved me! All of my calendar stuf had disappeared as well. I should know better than to do these updates when they just come out. I deleted exchange and added outlook. Thank you!!!!

My iphone is 17.3. MyiPad is 17.2 Since the update on my iPhone, both want a password for Mail Exchange account. When I enter it, it asks again. I have logged into Outlook on my Mac via the web and no issues. Help please.

Report the issue to Microsoft support, or look at their help site or talk to your IT admin if this is a work account.

Anyone else?

Tale to your IT folks. Exchange and Apple don't always work together very well. As they are the people in charge of the Exchange settings, they would be the place to start.

I have the same problem with my iPhone and ipad. My iPhone is still on 17.2.1 and my iPad is 17.3.

It has nothing to do with the update. The same thing happened about 6 months to one year ago.

It took a week the last time, but they finally fixed it.

We all know that Microsoft and Apple are not best of friends. I think that Microsoft has made changes that effectively block apple products from connecting to their system. Then apple has to find a workaround.

If I use Outlook on my iPhone, it works fine. But I don't like the calendar in Outlook on the phone.
