Outlook Stopped Working on Android? Complete Fix Guide

When Outlook stopped working on Android, it can disrupt your entire day—especially if you depend on it for work emails, meeting schedules, or important attachments. Many Android users suddenly face problems like the Outlook app not opening, crashing repeatedly, or failing to sync new emails. In some cases, Outlook opens but gets stuck on a loading screen, while in others it closes instantly after launch.

These issues often appear after a recent Android update, a buggy Outlook app update, or due to background restrictions set by battery optimization features. Corrupted cache files, incorrect sync settings, or even temporary Microsoft server issues can also cause Outlook to stop working properly on Android devices.
