Anyone using Microsoft apps on a Samsung Galaxy smartphone should pay close attention right now. Several reports indicate that well-known programs can suddenly cause issues.
Samsung has updated numerous Galaxy smartphones with the April update. However, since then, problem reports have been piling up on Reddit and in official support forums. Users describe issues with several Microsoft apps. The Authenticator is particularly critical because it is needed for two-factor authentication. If the app no longer opens, it can block access to secured online accounts.
Outlook and Excel Also Affected
According to reports, it’s not just the Authenticator that’s affected. Excel also fails to start for some users. The issues with Outlook vary. Some users can no longer access their accounts. Others report that their inbox doesn’t update. Still, others open emails only to see blank pages. This can quickly become a problem, especially for professional use.

Various Galaxy Models Affected
According to the article, Samsung and Microsoft have not yet commented on the difficulties. Therefore, it remains unclear whether the April update is indeed the cause. Many complaints coincide with the timing. At the same time, some users report similar issues even though they haven’t installed the update. Thus, other reasons are conceivable.
The reports do not refer to a single device. Instead, several models from the Galaxy series seem to be affected. Which smartphones are exactly causing problems and whether all errors have the same origin cannot be definitively determined from the current information.

A Temporary Solution Offers Hope
One user describes a possible workaround using Android System WebView. According to the report, Microsoft apps use this system component. It can be found in the system settings under the Google menu, where you can remove the installed updates. Afterward, restart the smartphone and reinstall the WebView updates.
This solution is not officially from Samsung or Microsoft, so you proceed at your own risk. Unofficial interventions can lead to further problems. Those who want to be cautious should wait for an official solution. Some affected users also report that a simple restart has already helped.
