This error can occur when a user is trying to click the edit button in a Microsoft Teams Tab. Here is one potential fix that I have been successful with. If you are receiving the bad request error when opening a word document tab can you try to remove the tab. Then click over to the files tab and re-add the document to a tab. This should also apply to Excel documents.
