Hi @Paru
Thank you so much for contacting Microsoft Q&A Forum.
Based on your description, I understand that you've lost access to Microsoft Teams and a shared folder right after a Microsoft 365 update, which is preventing you from performing your daily tasks.
To better understand the situation, could you please provide a couple more details?
- What operating system are you using on your laptop (e.g., Windows 11, Windows 10, macOS)?
- You mentioned being unable to access a shared folder. Could you please share a screenshot of the error message you receive when you try to access it? This will give us a clearer picture of what's happening.
In the meantime, here are a few standard troubleshooting steps you can try to see if they resolve the problem. Please try them in order.
- Check Access on the Web. First, let's see if the issue is with the desktop app itself or your account access.
- Open a web browser (like Chrome, Edge, or Firefox) and go to teams.microsoft.com > Try to sign in with your account > If that doesn't work, please try opening an Incognito or Private browser window and attempt to sign in again. This helps rule out any browser-related issues.
- Clear Teams Cache
If the web version works, the problem is likely with your desktop application. Corrupted cache files are a common cause of issues after an update.
- Please follow the official guide to clear the Teams client cache: Clear Teams cache
- Sign Out and Sign Back In
- Click on your profile picture in the top right corner of the Teams app > Select Sign out > Close the Teams application completely, then restart it and sign back in.
- Reinstall Microsoft Teams
If none of the steps above work, please try reinstalling the application as a final resort.
- First, uninstall Microsoft Teams from your laptop > Then, download the latest version
Please let me know how these steps go and provide the information I requested above. We'll figure this out.
