Slow Performance

Question

I am sorry to say but I guess the issues on Microsoft Teams does not seem to be taken seriously. Even I am having the issue that the Teams is very slow. It was slow even when I began using Teams for the first time.

I guess now it's high time you better check out what is going on. Please understand that I am having online class and soon will have exams via Teams. I don't want any issues during exams.

Hello DAA2,

Thanks for your post in Microsoft community. We do understand your situation under COVID-19 and mange online class and exams via Teams app. So regarding your issue, please check below suggestions.

1. Connect your system with different network (make sure there is no firewall or antivirus blocking Teams).
2. Open Teams Web App in InPrivate browser mode (Chrome or Edge) and check the performance status.
3. For Teams client, check your Teams client app is updated with latest version.

• To update Teams client app: Open Teams client app > click on your Teams profile picture > click on “Check for updates” and update your Teams with latest version.

4. Clear Teams cache by follow the below steps:

• Fully exit the Microsoft Teams desktop client. To do this, either right click Teams from the Icon Tray and select ‘Quit’, or run Task Manager and fully kill the process.
• Go to File Explorer, and type in %appdata%\Microsoft\teams.
• Once in the directory, you’ll see a few of the following folders:
• From within ‘Application Cache’, go to Cache and delete any of the files in the Cache location.: %appdata%\Microsoft\teams\application cache\cache
• From within ‘Blob_storage’, delete any files that are located in here if any.: %appdata%\Microsoft\teams\blob_storage
• From within ‘Cache’, delete all files.: %appdata%\Microsoft\teams\Cache
• From within ‘databases’, delete all files.: %appdata%\Microsoft\teams\databases
• From within ‘GPUCache’, delete all files.: %appdata%\Microsoft\teams\GPUcache
• From within ‘IndexedDB’, delete the .db file.: %appdata%\Microsoft\teams\IndexedDB
• From within ‘Local Storage’, delete all files. : %appdata%\Microsoft\teams\Local Storage
• Lastly, from within ‘tmp’, delete any file. : %appdata%\Microsoft\teams\tmp
• Once finally done clearing, you can now restart Teams from your local desktop and all cache will be cleared from the desktop app.

If still issue occurs, try to configure your Teams account in different computer and check the result. It helps to identify if issue is related with your account or with your device and network.

Thanks and regards,

maybe create a script or option in ms teams to do that? That's not something normal user is able to do or even look into those folders ;)
