Time of email no longer showing in mail app in Big Sur

Hey LalitaX, Thanks for posting your question about locating the email timestamp in the Mail app in Apple Support Communities! Where is it that you are trying to view the time within the Mail app? Usually if the window for the mail app is enlarged beyond a certain point you can see the time within the inbox to the right of the "Subject" of the email. Best wishes.

Hey LalitaX, Thanks for providing that additional information!

To get the date and time to show in that section you will go to the menu bar and select, View > Show Date & Time.

Best wishes.

As far as I can tell, a received message will show the time if it was received today; otherwise it will show the date ("yesterday", for example; or an actual date like in your screenshot).
