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

I tried it. First, it is through the Microsoft store so you may not need approval to get it installed. I didn't and we have a strict policy on extras. Second, it doesn't work very well. It made some odd translations for some of the text and if others are "reacting to chats with emojis it really gets funky. Microsoft just needs to act and fix this for the majority who want it instead of the minority who don't.

Thank you, I will give it a try.

to make your formula work for AM/PM had to change your "3" to a "6" to account for the extra characters
=IF(LEFT(RIGHT([@Input],6),1)=":",

           "["&[@Input]&"]", 

".")

and for whatever reason my teams post the time below regardless of who Person 1/2 is i had to change P52
=IF([@IsDateFormat]<>".",

  IF(A8=$A$2,

               [@IsDateFormat] & " " &A8,

         IF(A10="Edited",

               [@IsDateFormat] & " " &A11,

         IF(A8=$A$4,

               [@IsDateFormat] & " " &A8,

               "."))),

".")

I think some of your formulas and fields are redundant but assuming you kinda just slapped this together to get your desired result. i appreciate the start and ill retool to my needs when something else about teams copy pasting pisses me off

Glad to know that it assists a bit and gives some ideas :)

I think I know why, perhaps you are using Compact Chat Density? (Settings > Chats and Channels > Chat > Message Density > Compact)

I tested in mine with compact and when I copy it does place the time at the bottom of the name for both the Person1 & 2.. I did not realize that before.

I can no longer copy and paste the chat nor save the chat's date/time. Cntrl C and Cntrl V isn't working either.
