Apple Mail on iOS15 / Outlook.com MFA Application pwd

Mine was already correct. Though for about a week I haven't gotten the popups unless I reboot. Just installed iOS 15.0.2 and it prompted me as soon as I opened the mail app. I've put in my password about 25 times.

Since this is an Apple issue and there’s no fix in the foreseeable future, the solution is simple. Deleted my exchange mail account from Mail, and installed Outlook for iOS. Settled. So far no password popups.

I checked mine and the time zone was correct (Eastern). But I clicked on the link anyway and it showed me a map where my calendar was set to Pacific. I clicked on Washington DC on the map and was able to change my calendar's time zone to match my email time zone.

I just did this so I don't know if it works or not. But I wanted to follow-up to this post and tell people to click on the time zone even if it's correct since the calendar may not be. Let's hope this works!

Been having the same issue ever since updating to iOS 15. I have 3 mail accounts on my iPhone SE. 1 Office 365 Exchange with MFA enabled, 1 Zoho account with MFA enabled and 1 Zoho account with no MFA. The only account having the issue is the Zoho account with MFA enabled. I have the re-enter the app passcode about once every 2 days. Ironically, the Office 365 account is fine unlike most people here. Even though MFA is enabled on the Office 365 account I don't have to use an app passcode because the iPhone can integrate with the "modern authentication" Microsoft uses. With Zoho I have to use a generated app passcode and that's the one with the issue. Oh and I have all 3 of these accounts on Outlook on my Windows 10 desktop, no issue there.

Sorry, no answers here, just wanted to provide another data point.

I have been experiencing this same issue since I've upgraded my devices to IOS15. The issue continues to happen for my work email on an Exchange server. The issue is happening on both my iPhone 11Pro and my iPad. Deleting the email account and re-setting it up has not solved the issue on either device. It is frustrating.

Good eye! Mine actually said Pacific and when I clicked and it brought up the map it had me somewhere in western Canada. I’m in NC. It probably goes without saying, but it’s probably best to reboot all connected iOS devices after making the time zone correction. Fingers crossed that this is the fix as I’m over 24 hours now without the popup.

The fix is easier to do on a desktop, but can be done on Safari. Open a browser or Safari and go to iCloud.com and log into your account. Choose the Account Settings link in the top middle of the page. At the top right of the page your time zone should be displayed. Even if it looks correct you need to click the time zone. That will bring up a map where you can click on your correct time zone. If you are in Safari don’t click the map, just click in the box on the map with the city name. That will pop up a list where you can choose your correct city closest to you an in your time zone. I clicked on Washington DC since I’m in Eastern time. Click Done and look at the top right to verify the time zone is correct. Then reboot all iOS devices and cross your fingers.

is there any way for us to contact Apple about this problem?

my boss already asked me to fix this problem.

i tried with my personal devices (2 iPads, 2 iPhones), all of them didn't ask for password regularly.

only 1 known case at my workplace right now but he's the boss

We have the same problem with my wife’s work exchange email account on her iPad Pro. The lockout actually locks all her remote access too and her IT dept is getting frustrated after unlocking several times. They told her not to use the iPad anymore for work. Now I am in the dog house for updating this new expensive M1 iPad Pro because she cannot get work done.

Apple software team needs to fix this !

I have removed my exchange accounts, and log in again using sign in option and not setup manually. So far so good. It seems Microsoft has new security policies that grant access to apple.

try that an good luck

That's incorrect. We're on-premise exchange and I'm one of the exchange Admins. There's been no patches applied. No new security policies or anything changed in months. Test devices on ios 14.x aren't having the problem. ios 15 is the problem.

Unless Apple doesn’t want me back using Mail, they can ignore this. My work place uses Exchange and I can’t change that. After countless login issue, I have downloaded Outlook for iOS and there has been ZERO issue.

Time/location isn’t an issue for folks outside North America I think and that hasn’t been a fix as well.

I can confirm, after removing the accounts from Iphone and Ipad, and setting them up again worked for me.

i have also re adjust the time and location on Icloud.

when setting up exchange accounts, use login and not configure manually.

login will open Microsoft site, follow the instructions.

i have been many days without any issues.

I am literally experiencing this daily and bc our exchange email account is attached to our peg’s active directory, it’s also locking me out of my account bc it’s reporting incorrect password. So frustrating.

I have updated to iOS 15.0.2, deleted my ms exchange account, rebooted the phone (12 pro max) and reinstalled the MS exchange account.

looks like i’m down to being asked 1-2 times a day for my exchange password.
