iPhone keeps asking for Outlook password

My iPhone 13 with the 16.7 operating system was operating fine until last week. It now continually asks for the Microsoft Outlook Exchange password. I enter it and it keeps asking. In addition, now if I enter an appointment or contact on my iPhone, it no longer syncs and updates to Outlook. If I enter a new appointment or contact in Outlook, then it eventually updates to my iPhone as long as I keep entering the Outlook password multiple times. Strangely enough, email seems to be working OK in all of this other than always being asked for the Exchange password. I doubt this is a Microsoft issue. Apple - please respond and let us know what's going on and when to expect a fix

Thanks for trying! I think it does make sense. Microsoft isn't going to let users bypass their legal department simply by using the iPhone app.

Microsoft should be sending out email notifications to get people to adopt new T&C.

Apple should not assume that login has completely successfully when the account isn't in a usable state (ie T&C hasn't been accepted).

And unlike the other accounts, there seems to be no way to update my password on my iPhone. I see the four accounts on the others. I click in the name click on my name again and there’s an opportunity to update the password in settings.

But when I click on the Outlook account under my name, nothing happens. Over the years the location for updating your password or the network settings on the phone or computer has changed multiple times which gets a little confusing but I can see where I can do it right here in the phone for my Gmail accounts but not outlook.

Checking the new Outlook agreement sounds promising. I logged into my Microsoft account and found the Microsoft Services Agreement. It states you automatically agree to it if you use any of the items after September 30th. Can you specify if this is the agreement you are referring to as there is no way to accept or decline it.

Not sure if it is the reason, but I logged in to Outlook Web this morning and I was shown a new Microsoft terms and conditions. I accepted them and I have not seen the password prompt again. Let’s see what happens tomorrow.

But it will make sense if thats the culprit

I solved this issue in Apple Mail by logging into Microsoft.com for each outlook account, accepting the new EULA, turning off 2FA, reentering the account password for each account in iOS settings for Mail and accounts. Hope this helps others.

I have accepted new Eula yesterday via the web on all of my Hotmail/live accounts and I still get the password prompt today. So, curious to see how everyone else got this fixed permanently by doing that.

Could something have been pushed overnight and no notification show up on my phone or iPad? Oddly both are working fine this morning. Neither asked for my password. Maybe I shouldn’t boast just yet, but finding it surprising.

Mine is working too.

Likely something was fixed in their infrastructure which I think makes sense as it was impacting so many levels of iOS. That or maybe MS fixed something in the systems.

Nice not to see the message. Of course now I've jinxed it. LOL

So far so good after logging in to Outlook in a web browser and accepting the new agreement. Both mine and my wife’s phones stopped prompting for Outlook passwords. I also removed and re-added both accounts to both phones, using the Outlook option, after accepting the agreement in a browser.

Folks...I think i have a solution. After 6 hours on the iphone with Apple Support and a ticket to their engineering, they told me the issue was caused by "antivirus" apps on my phone. They asked me to remove Norton, Norton VIP and Fing. I did this skeptically but was desperate. Anyway, I'm 3 days in and everything is working great.

Worth a try, worst case you add back those apps.

Shoot! I thought this was the silver bullet for everyone.

I spent a bunch of time on the phone with Apple Support. After hours and hours, they finally had me send a diagnostic to them which an engineer reviewed and picked out 3 apps (two of which I had no idea were considered to be antivirus). The only thing I can suggest is that you have them do the same. Maybe you have similar apps that are considered to be antivirus and dont know it

Best of luck...

Yeah.. I think Apple fixed it. I tried every suggestion listed here, including the Eula agreement and I was still experiencing the password prompt issue until the last 1-2 days. Up until yesterday, I was so fed up with it I clicked “cancel” when I had the prompt. Now, it doesn’t show up anymore.

Thank you for starting this thread. I have had the same problem on my iPhone for more than one iOS update. My experience is that Microsoft office 365 constantly asks for re-authentication for adding apps on outlook on the Mac, as well as re-adding accounts and authentication on iPhone devices. While, this might be an Apple problem, hypothesis is that this started with a release from Microsoft on office 365 within the last six months.

RESOLVED for me, anyway (read below)! Ok...this drove me absolutely nuts! My 14 Pro Max was replaced under warranty...a phone I had not updated since it was new a year ago (sorry but if it ain't broke I'm not updating and even if it is, I think 5 times before updating-too many times features are lost in updates!!!). I love how we are told it is a hotmail/Microsoft issue...that is completely wrong...none of my older iphones have problems...they are not on ios17xxx@! I don't like having to install apps that I don't plan to use just to fix problems, but in this case I did. I have 8 different hotmail accounts and every time I would open the mail app on my iPhone it would blow up with re-enter password prompts TWICE for each of them!!! I would hit cancel on each and they would pop up again for each. Ok, here's what worked for me:

(iPhone 14 Pro Max running IOS 17.0.1)

1) SETTINGS --> GENERAL --> TRANSFER OR RESET IPHONE --> RESET --> RESET NETWORK SETTINGS

2) Install EDGE from App Store, add hotmail accounts in EDGE; checking 'stay logged in on this device' for each

3) SETTINGS --> MAIL --> ACCOUNTS --> re enter passwords for each affected account.

4) Tested, all working fine.

5) Delete EDGE app.

All working fine since...why, I am not sure?! (crossing my fingers)

I hope this helps someone else.

Good Luck All!
