Additional file-related features and issues within Microsoft Teams for business
Hello AC_89,
Microsoft is aware of the issue where the option to open files in the desktop app is missing in the new Teams. This could be due to not meeting one of the three prerequisites:
- You must be using the Teams desktop app for Windows or Mac.
- You need to have the corresponding Office desktop apps (Microsoft Office 2016 or later) installed from the Microsoft 365 portal.
- You must have an Office 365 E3 or E5 license.
For more details, please refer to the support article: Desktop app option is missing when editing Office files in Teams - Microsoft Teams | Microsoft Learn
Hope this helps!
Regards,
