How to fix Microsoft Store and Xbox app error 0x803F8003?

Issue: Hello, I ran into issues with Microsoft Store. To be more precise, every time I attempt to download or update any of the apps, I get an error 0x803F8003. How do I fix this error?

Solved Answer

Microsoft Store and Xbox app error 0x803F8003 is a common issue that Windows users often encounter, typically when attempting to update or download apps from the Microsoft Store. It is a software bug that signals a discrepancy between the user's device and the Microsoft server.

The causes of this error can range from temporary server issues to incorrect account settings. Certain background processes might interfere with the Microsoft Store's functionality, leading to this error. It could also occur due to insufficient storage on the device, leading to the system failing to accommodate updates or new downloads.

In some instances, users might face the same 0x803F8003 error while trying to launch a game via the Xbox app or Game Pass. This problem is not just confined to a single game; it can happen with any game, regardless of whether it's a newly downloaded one or an already installed one.

The error can occur due to a variety of reasons, such as licensing issues, internet connection errors, or a discrepancy between the game's local files and the Microsoft servers' files. Miscommunication between your Xbox app and the server may prevent the validation of your game licenses, causing the 0x803F8003 error to appear.

In some cases, the error might be due to a temporary glitch on Microsoft's end. When servers are down or undergoing maintenance, you may be temporarily unable to launch games via the Xbox app or Game Pass. Also, if your internet connection is unstable, the Xbox app may struggle to verify the legitimacy of your game licenses, leading to the error.
