Microsoft Teams is a powerful collaboration tool, but sometimes it can misbehave—causing issues like missing messages, failed sign-ins, stuck status, or performance problems. Clearing the Teams cache is a simple yet effective way to resolve many of these issues.

In this article, we’ll explain what the Teams cache is, why you might need to clear it, and how to do it safely on Windows, macOS, and mobile devices.

🗂 What is the Teams Cache?

Microsoft Teams stores temporary files and settings in a cache folder to improve performance and reduce load times. However, if this cache becomes corrupted or outdated, it can lead to:

  • Sync issues (e.g., missing chats or teams)
  • Login problems
  • Stuck presence status (e.g., “Out of Office” or “Busy”)
  • Application crashes or slowdowns

Clearing the cache does not delete your data; it simply forces Teams to download fresh information from Microsoft’s servers.

🛠 How to Clear Teams Cache

🖥️ For Windows (Desktop App)

1️⃣ Close Microsoft Teams completely

  • Right-click the Teams icon in the system tray (bottom-right of your screen) and select Quit.
  • Or open Task Manager and end any running Teams processes.

2️⃣ Open the Teams cache folder

  • Press Windows + R to open Run, then type:
