How can I export a long Microsoft Teams chat?
I would like to export the entire history (thousands of messages) of a conversation from Microsoft Teams. There is no "save" or "export" functionality evident in the Windows client. I found some forum posts that suggested using the browser interface and printing to PDF, but when I did that I got only the most recent few messages, not everything. "Select all" (control-A) did not select messages in either.
I tried selecting a batch of messages manually, copying, and then pasting them into some other application, but got no results in either MS Word or Emacs -- it acts like the copy didn't happen. I can copy and paste individual messages successfully, but that's not a viable approach.
I found some posts that suggest the existence of an admin tool for exporting, but I do not have admin access. I'm just a regular user. I also found some references to exporting my data, which I assume might be to comply with data-portability laws, but I want the whole conversation, not just my piece of it.
How can I archive a long conversation efficiently?
