Hi @Koussaï Mbiriki
Have you set the default open method of files to browser on the client side?
Depending on your description, here are a few things you can try:
- In the Teams desktop app, go to Settings & more (icon in the upper-right corner) and select File > File Open Preferences.
- From the drop-down list options, select the default app where you want to open your Office file, such as Teams or Desktop App.
- If you're using Teams on the web, you can choose between Teams and Browser.
- If the link is a SharePoint link, it will automatically trigger a session through the browser because SharePoint is browser-based.
