How to Clean Microsoft Teams Cache & Fix Common Problems?

Remote work has become a new norm around the world, with many businesses allowing their employees to entirely work from home, or through hybrid opportunities. The need for remote work has led many individuals and businesses to adopt cloud-based video conferencing and team collaboration applications.

Microsoft Teams is one such application that enables individuals to share ideas, collaborate with the team, and communicate in real-time. Teams is pre-installed on Windows 10 and Windows 11, so you don’t have to download anything separately. Teams is scalable and convenient, and filled with a host of features that improve your productivity and efficiency.

Much like any other computer application, Teams is prone to errors, audio-video issues, crashes, and performance issues. You may be able to get rid of these issues by cleaning your cache.

Possible Scenarios Requiring You to Clean Teams Cache

There are several reasons why you might want to clean your Teams cache. Here are some of the possibilities:

  • Improve Performance: Teams cache is meant to facilitate faster access to its data and improve the overall performance. However, cache contents can get corrupted, such as when your computer abruptly shuts down, or your Internet connection drops too frequently during video conferencing. When that happens, it impacts your performance. Cleaning the cache might help get back the lost performance.
  • Troubleshoot Log-in Issue: Are you unable to log in to your Teams account? If so, it’s a good reason to clean your cache. The corrupted cache may prevent you from logging into your account, even with valid login credentials.
  • Voice & Video Conferencing Issues: Voice and video conferencing issues are too common on slow-speed Internet connections. However, corruption of the cache contents can also contribute to such issues. You can resolve them by simply cleaning your cache.
  • Other Diagnostic Purpose: At times, Teams may not work as expectedly. If your Teams is becoming unresponsive, crashing, or displaying errors, cleaning the cache can resolve it.
  • Reclaim Lost Storage: This shouldn’t be a scenario for most users, as Teams cache may not take significant storage. However, if you’re running extremely low and unable to perform basic tasks, it can be a breath of fresh air.

Is It Safe to Clean the Microsoft Teams Cache?

Absolutely, it’s safe to clear the Teams cache. The cache is a temporary location that contains files stored for short-term use. They are written for a variety of reasons, and it’s safe to delete them to diagnose specific problems with the application. However, it’s best to have your sign in credentials in-hand, just in the case.

Will You Require Signing In to Teams After Cleaning the Cache?

No, you will not need to sign in to your Teams account again after cleaning the cache. Cleaning the cache does not clear your sign-in credentials.
