"Something Went Wrong" when opening Microsoft 365 Excel files

Question

Whenever I try to open an excel spreadsheet through Microsoft web version 365, it says "Something Went Wrong" and then says "You can now close this browser tab" and closes. I can open the file in a local client version of the software, but others in my company don't have the client versions. I can also open Word docs and PowerPoint presentations through the O365 without issue.

Answer 1

Found out that this issue was resolved by Microsoft and was a Microsoft Temporary Outage. Problem resolved.
