A few comments in the blog post regarding a recent issue whereby users may become stuck and see repeated sign-in prompts when using iOS Mobile Application Management (MAM) applications.
If impacted, please look for: IT511115 in your tenant's Service Health Dashboard.
We've received confirmation that the fix is now available on the Apple App Store. Users need to update their Outlook iOS app to version 4.2303.1 or higher to receive the fix, and users need to launch the updated Outlook app first before any other MAM app to prevent impact from reoccurring. If a sign-in prompt loop occurs, users can sign out and then back in to break the loop.
If your issue is different from what has been posted, or you don’t see this incident in your SHD, kindly reach out to us with more details so we can understand your situation and assist you further. Thank you!
