Hi @Terry Chan ,
Is there any way to have VBA/Macros working within Teams to avoid having to open the Excel file in Desktop App? A workaround if not directly possible?
I am afraid no, it's currently not feasible to use Excel VBA/Macros within Teams, and as far as I know, there's no other alternative available except working on the file in Excel desktop client. Below is a relevant post I found in the dedicated feedback portal for Microsoft Teams. I've already voted it and you can also add vote or comment there. Hopefully this feature can be added in the near future.
Support macros and VBA in Excel workbooks.
Is co-authoring be possible in Desktop App?
Are you referring to co-authoring Excel files in Teams application? If this is the case, yes, it's supported.
