Currently users are unable to edit Office template files (.potx,.xltx,.dotx) in Teams Files. For these format files, if modification is needed, users need to download the files from Teams, modify the content, then upload the file again to Teams Files.

Current workaround is user can select the file then choose "Open in SharePoint", then modify the file in SharePoint. But this introduces additional work for users.

We would like to have this feature, enable edit of Office template files (.potx, .xltx, .dotx) in Teams Channel directly like other normal Office files (.pptx, .xlsx, .docx).
