Hello @all!
Hope someone can help me solve this wired issue.
We have about 80 Intune Enrolled Devices. Just iOS.
My Users now gets pushed the Outlook App by Intune since we changed to this app.
Before they downloaded it from AppStore or Company Portal.
Outlook connects to Exchange Online.
We have a Outlook App Configuration Policy where we set under E-Mail Account configuration:

First thing came to my mind, do you have Conditional Access Policy that conflicts with your setup? Do you see any 'Device Access Rules' under Mobile section in Exchange Online?
Last resort, it could be App config policy, do you have legacy authentication disabled in your tenant? I would check the sign in log from Azure AD-> Add Filter-> Client App-> Check all the boxed to see if somehow these Outlook apps are trying to use something other than Modern Auth. This log should shed some light about the issue.
Good Luck!
Moe
Thanks!

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.
