Trending Of Mac Mail App Keeps Crashing New Update 2021. If this doesn’t do the trick, the next step to try is to force the mail app to start over. Mail crashes as soon as it starts.
I’ve found that deleting mail.app’s “envelope” index seems to alleviate crashing or hanging. It's possible an incompatibility exists between mail and one or more of the email services you're using. If any, try to update the same to see if problem occurs again.
Test the mail app in a new user account.
