Microsoft is known for making quality software that doesn’t often run into errors, but when it does, it can cause major problems for the end user. Whether it’s Windows or something simple like Teams, these are essential programs that are used on a day-to-day basis and encountering fatal errors can cause issues. 

In this article, we’re taking a look at the error code 53003, its causes and what you can do to fix the problem. 

What causes this error code?

The error code can be triggered by a number of things, but the main reason lies in a conditional access bug in Microsoft’s servers. Other common causes include:

How to fix this?

Here are seven fixes you can try out. 

Check your internet

When you see an error like this, you should first check if you’re connected to the internet. If you’re on WiFi, make sure you have a stable signal and an active internet connection. If you’re on mobile data, check to see if it’s enabled and that you have good network coverage.

Try logging in again

Invalid or outdated credentials in your Teams app can also cause these errors. Regardless of the platform, try logging out of teams and signing back in again to see if that resolves the error. 

Check for outages

A server outage from Microsoft’s end can also cause this error. You can check Microsoft’s Server Status website for Office applications or a third-party website like DownDetector to see if Teams is working as it should. If Teams is down, all you can do is wait for the service to come back online before giving it another shot. 

Clear the cache

Clearing the app’s cache can eliminate any corrupt files or data that might interfere with Team’s functionality.
