Windows on Arm PCs lose Outlook and Teams access
The latest software updates are meant to bring efficiency and new features, but for some users, they arrive with a frustrating glitch. A recent Windows 11 update appears to have caused significant disruption for those running Windows on Arm PCs, specifically targeting core applications like Microsoft Teams and Outlook.
The trouble started immediately following the rollout of KB5121003, which began shipping this month on Patch Tuesday. While the goal of the update was presumably to improve the user experience, many users on ARM-based systems found themselves dealing with unexpected shutdowns and errors right when they needed their communication tools most.
The symptoms reported were specific: when users attempted to open Microsoft Teams or the new Outlook, the applications would close almost immediately. This disruption was particularly noticeable with the new Outlook interface, although it was noted that the classic version of Outlook remained functional on the affected machines.
This isn’t an isolated incident. Reports emerging from the community indicate that this issue is affecting a variety of Windows on Arm devices. Users running systems like the Surface Laptop 7 and Omnibook 3, which utilize Snapdragon processors, have encountered similar instability following the update.
One user detailed the perplexing cycle of frustration. After initial setup, Teams might work fine one day, only to face a blank white screen and an immediate close the next. Attempts to roll back updates and factory resets offered temporary relief, but the core problem persisted, leaving many wishing for a stable fix.
The mystery remains: there is currently no clear explanation from Microsoft regarding why this issue is limited to ARM systems. While reports suggest a possible common factor across various Snapdragon and ARM64 devices, official channels have not confirmed a known issue related to KB5121003 in their release notes.
As users wait for official confirmation and a resolution, the immediate necessity is to manage workflow around this technical hiccup. For those affected, the temporary solution involves looking for workarounds, potentially utilizing unaffected versions of Outlook and Teams while the system administrators work toward a stable patch.
