Using Outlook for iOS in business environments for email and scheduling
I have an issue that may be the same!?
Using the IOS mail client with two O365 accounts. I have just been prompted to update my password / re-authenticate my accounts.
If I go to mail settings and re-enter my password it pops a message advising it wants to use Windows.net to Auth.
1st account…usual experience and it works
2nd account it pops the window and appears to use the cached values from the previous account, as it flashes up and disappears immediatly and fails to Authenticate.
I have now lost access to my personal email on my phone!!
