One thing- I can't copy and paste from documents within the microsoft teams.
Ex: When I open a document it opens through a document viewer. I can't use the copy feature to copy a name on a resume and then later paste on a Google open tab.

I tested this and was not able to replicate the problem in read-only or edit view in the Teams viewer. Is the file in a particular format other than word?
