Outlook for iOS Account blocked after password change
If a lot of failed sign-ins happen in a short timespan, the account can get locked as specified in https://portal.azure.com/#blade/Microsoft_AAD_IAM/PasswordProtectionBlade
I would recommend also disabling legacy authentication using Authentication Policies in Exchange Online. Because this would make sure an account isn't locked due to failed sign-ins while using legacy authentication
But last malicious sign-ins were on 2th May but it is still not working.
If I create this policy on Exchange, what I think is a good idea, I think I will get troubles with some old services what use smtp...?
Thanks, Philip
Hi All,
I found a solution.
The Problem was that the iPhone saves Accountinformation in Key-Chain.
I downloaded the OneDrive App.
Open Settings -> OneDrive -> Clear Account Data
Then opened the OneDrive App to delete data.
in Azure AD I clicked on Revoke MFA session and reinstalled Outlook.
After this steps it worked.
This article pointed me to the right direction:
A customer of mine had a similar issue (which is why I came across this page). After a password change, a user's account got repeatedly locked out when synchronizing Outlook on an iOS device. The sync started but stopped after some time with the message that the account is locked out. Factory-resetting the iOS device or replacing it didn't help. 2 out of 60 users affected. The feedback I got was that the issue was finally fixed when replacing German special character (ä,ö,ü) in the passwords. I can't give any more background but describe the issue to prevent others from getting crazy.
