Hello, by executing troubleshoot step 2 (signing out, and sign back in) the app bar on the left side of my screen was restored. Thank you.

Hi @Erik Majoor,

Good day and thank you for posting in Microsoft Q&A Forum.

Regarding your description, could you please share a few more details to help us better understand your situation?

Firstly, could you kindly share a screenshot showing the missing app bar in Teams?

Also, may I know which version of Teams are you experiencing this behavior on? (Teams desktop app, Teams on the web, or Teams on mobile). If possible, could you also check the other versions to see if the issue persists across them?

Additionally, if you're using the Teams desktop version, I’m aware of a setting that can affect the visibility of the app bar depending on the window size (as shown in the image below). If this toggle is turned on, resizing the Teams window beyond a certain point may cause the app bar to disappear. Could you please check and share whether this setting is currently enabled?

In the meantime, if you’ve checked all the settings and the issue still persists, I’d recommend trying some troubleshooting steps which may help:

1- Check for updates to ensure you’re using the latest version of the Teams app.

2- For the Teams desktop app, try signing out and signing back in, or perform a reset/repair/uninstall of Teams in Windows Setting. You can also try clearing the Teams cache by following this article: Clear the Teams client cache.

3- For Teams on the web, you can try clearing your browser cache or logging in via an incognito/private tab.

4- For Teams on mobile, you can try reinstalling the app to see if the issue still occurs.

Thank you for your time, I'm looking forward to your response
