I am not able to copy and paste Teams message with Time and sender name

I'm restricted from commenting on the link you provided. Someone needs to fix this stupid part of the Teams update, quick! Total roadblock to effective communication in an organization!

Yes, it's a major annoyance. I'm puzzled why it hasn't been fixed.

I tried the option to hold the mouse down while Ctrl+C and it does not always copy a complete message.

It horrible, but I've had to break down and just take screenshot images of chats for an accurate history now. Talk about data size bloat!

This is where companies get too big and don't know how to properly prioritize work for customers. Shame shame.

Even if a bug is supposedly "minor", if most customers are experiencing it every day and impacting productivity, then that should make the bug priority HIGH.

Heck, even if a bug is super minor, like a misspelled word or slightly skewed control on a form...... if customers see if ever day, then it screams poor quality and the perception of the product and company take a big hit.

This concept seems to not be understood at Microsoft.

This is an easy one as we just want basic copy/paste functionality back. Perhaps this customer will be going back to Slack soon as I can start campaigning for that.

I didn't read through all the comments, so this may have been mentioned already. This isn't broken, this is decision put in place by the Teams group.

Summary

Teams has removed timestamps and author names from copied messages to reduce clutter. Users who need detailed message transfer should use the Forward feature or Teams Export API. This change is already in effect, and organizations may need to update training materials accordingly.

Many users have voiced frustrations over copying messages in Teams, particularly the inclusion of metadata like names and timestamps. Customer feedback has been clear, signaling that this feature was adding more noise than value to user workflow.
