Conversations involving multiple participants, allowing collaboration and information sharing in Teams
Ran into the same problem with the recent Teams update.
I use a Mac, but maybe the workaround is the same:
• Highlight the text you want to copy with your mouse, and continue to hold down the mouse button—don't let up.
• Then use your shortcut keys to copy the text (command+C), and then let up on the mouse button.
• Paste it where you need it, and it should include the timestamp and identity.
