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

My specific issue has been RESOLVED!!

When transfering my iPhone 13 to my iPhone 16, I have VPN services on. Turning it off would only come back on automatically! Here's my reply post on Apple Community. If you cannot get some APPs to install on new iPhone and iOS 18, this might be the problem. It was absolutely my problen and is now solved.
