Why in Teams you are unable to copy the time stamp and name of the person anymore.

Yes, that sucks.

well thats sucky of them their new feature is not well liked by us the end user

Amen to that, shockingly tone deaf attitude from Microsoft

This is will not be corrected as it is a design feature, not a bug.
Case resolved last Sept 2024
Microsoft 365 Alert – Service Degradation – Microsoft Teams – Users may be unable to copy and paste specific metadata when copying and pasting messages in Microsoft Teams –RESOLVED – NHSmail Support

"Final Update: 05/09/2024 09:06:00 AM – The investigation is complete and Microsoft have determined that the service is healthy. A service incident didn’t actually occur as we determined the change in behavior to be by design due to a change we made to reduce the noise of metadata when copying and pasting messages in the Microsoft Teams desktop and web clients. For further insight, please reference the Message Center post under MC878422."

¡Micro$oft $uck$!

If you are talking about the summary lines and sender + time sent being on two separate lines, Outlook email (likely Word too, and any editor with wildcards) Find / Replace can take clean that up. Yeah, it's kind of a slow-down, but at least it works. (Plus, once you enter the Find and Replace pattern in Outlook, the dropdowns should let you pick either if you have to do this for multiple chat copy/pastes.)

Here is my .txt file notes on what to use for that:

Find (turn ON options > use wildcards!):

^13[^32-^126]@ by [A-Z][a-zA-Z -]@, [A-Z][a-zA-Z ()]@^13

Replace with:

^13

Append the time with the user who said it (remove the newline after the name). Example:

"Lastname, Firstname

3:23 PM

"

Find (just the time portion of it and surrounding newlines):

^13([1-9]{1,2}):([0-9]{2}) ([AP]M)^13

Replace with (note there is a preceding space inserted to separate the time from Firstname on the previous line):

" \1:\2 \3^13" Remove the quotes. I just put them there to show the preceding space.

You'll have to find the right pattern for 24-hour time.
