Based on our research, this seems to be a common issue that many users are facing. There are a few possible solutions that you can try:
- Make sure you have the latest version of New Teams and the Office desktop apps installed on your computer.
- Check if you have the option to change the default file opening preference from an individual file’s menu. Right-click the file, select Open, then select Change default. Choose Desktop app and Save.
- If you don’t see the option to change the default, you can try switching back to the old version of Teams for now. Click the three dots in the top right corner of the Teams window. Select Settings. Under General, toggle off the option to use the new Teams.
- Alternatively, you can open the file in the browser first, then click the Open in Desktop App button on the top right corner of the file.
Meanwhile, to solve the issue more quickly, we recommend you give the feedback in Teams UserVoice. Many features of our current products are designed and upgraded based on customers’ feedback. With requirements like this increase, the problem may well be released in the future.
