Outlook.com issues after iOS 18 update

I saw this happening in the past too.


Outlook.com is not working properly after iOS 18 update.


I tried this with Safari and Chrome on iPhone 14


  • Login is possible.
  • Reading a message is possible.
  • Browsing folders and its messages is possible.
  • Writing a new message is possible.


  • Refreshing the page sometimes won’t work
  • It throws a random error and forces you to close the session and start again.


  • Responding a message won’t work.
  • Forwarding a message won’t work.
  • Moving a message to a folder won’t work.

For the 3 above, the page just quickly refreshes or creates a non-stop looping and finally throws an error.


Issue is between iOS and Outlook.com (it also won’t work with the Outlook app).


Clearing cache, restarting, etc (all basic troubleshooting) didn’t help.


I’m capable to manage my mail (responding messages) only while using Outlook.com on my PC.


Something similar like this happened in the same phone, with other iOS update (16 something…)


Anyone facing the same?

iPhone 14, iOS 18

Someone@hotmail.com has worked since 1993 without fault. After upgrading my iPhone 13 Pro to iOS 18 someon@hotmail.com will not work. IMAP reports problems with password. Deleting account only caused further problems. iPhone will not allow recreation of the account. IMAP is not happy/does not support password. iPhone XR which has never had a hotmail account works perfectly. Does anyone have any idea?

Lucky you! I was able to replicate the issue on both Safari and Chrome (I didn’t want to install also Opera for testing purposes, as well as for any other browser options available).


I use apps at the minimal level on my phone (don’t even use any social media and I feel good about that too).


Mail app is now used for the time being, but only ‘till any hot-fix is made available, so I can come back to mail over Safari, only, as in the past.

But you are reporting issues with Mail app or Outlook app, right?

The original post was created to report issues with mail-over-browser use.

I did mention that I tried testing my account with Outlook app too, but just for testing purposes. It didn’t work well, by the way.


I always liked to manage my email over browser, only, not relying on apps.


Exceptionally I had to setup my Outlook account with Mail app. Otherwise I couldn’t respond to messages, pure and simple…

I have been trying for 8 days to get logged back in to my Microsoft account via Edge and the Microsoft Authenticator. No luck. At this point I have become extremely agitated. I FINALLY got in touch with Microsoft tech support. They say it is purely an Apple issue. I believe they are correct. I have reset my Microsoft password and uninstalled and reinstalled that authenticator numeros times. I can log in to my Microsoft Account on my Macbook M3 Pro, My 12" iPad and my Desktop Windows 11 PC without an issue, so it's not an account issue. I simply cannot log in on my new iPhone 16 Pro. I keep getting an error in Edge and the Authenticator "too many attempts".


Before I go completely mad someone from APPLE fix or respond to this issue. I absolutely need to get logged in to my Microsoft account on my iPhone 16 Pro.


I had zero problems on my iPhone 13 Pro running iOS 18. Please help!

I cannot login to outlook.com on Edge, Safari or Chrome. All those browsers want me to login to my Microsoft account or sync my setting. Upon clicking on and trying to login to my account on Safari or Chrome the screen goes blank, never to recover. When I try on Edge, it want me to use the Authenticator, which of course I cannot do either because it wants me to setup my account, which I cannot do because it will no log me in due to "too many attempts".


I cannot login to outlook.com nor any Microsoft address without first logging in to my account. It's a vicious loop of going no where. Anything associated with Microsoft on my phone is fubar'd.

No Word, no Excel, no Outlook or anything associated with my account/syncs are possible. This issue is "only" on my iPhone 16 Pro! My iPad running 17.7 has no issues!


I fear I may have to wipe my new iPhone 16 and just start from scratch, which I deeply dread.

Hi again jackzero.


I had a similar issue - like yours, but it affected me while using my iPhone and my PC as well.


When I browsed around, at that time (about a bit more than a month ago) to understand the case, I just realised I was not alone. I read about people facing the same.


After managing to get support from Microsoft, they have investigated my logs (on their side), and came out with the reason that my account had simply ‘stalled’.


They have done some kind of reset, that allowed me to get back to my mail, without the ‘looping’ thing.


Definitely not your case, as you are capable to use your account on your iPad, right?


I hope for the best, and in case you plan to report something to Microsoft, you can mention the ‘stalled account’ scenario. You never know…
