Hi Chacquie,
Based on your description, when you view an Excel file in MS Teams, it will show the scroll bars but the file will not display. May I confirm if you can see the Edit button in the upper right corner of the window (like below picture)?
If so, please try to click on the Edit button and try the second option to open this file and edit it in Excel app to see if this file can be correctly displayed.
In addition, if you cannot see the Edit button, please download this file and check if you can open it correctly in Excel app.
Both above methods will help us to narrow down if this issue is related to the Excel file. Moreover, if you can open/view this Excel file without problem, then I need to collect following information with you:
- If convenience, please connect to a different network and check if there are any changes.
- Could you please provide us specific information about how did you product “a local install of MS Teams”?
- Please check if the issue persists if you sign in web Teams through this link: https://teams.microsoft.com/.
- Does this issue persists to all Excel files or just some specific one?
- Did you receive any error message? If so, please send us a screenshot of the error message and a screenshot of the issue you are encountered.
- What’s version of Teams do you use? Please send us a screenshot of the version information like below picture. See: click on your account in Teams, About, Version.
Thanks for your understanding.
Regards,
Jennifer
