If you launch the Mail app on your macOS and it keeps crashing, here's the quick fix.

These three steps are very safe to do and will not harm your Mail or Mac in any way.
- Go to
~/Library/Mail/VX/MailData
using Finder or Terminal.
Hints:
- On Finder window, press Cmd+Shift+G to quickly go to the folder you want;
- VX: Depending on your Mail app version, for example, Version 14.0 (3654.120.0.1.13) shows V8 on the file system.
- Delete any file that begins with āEnvelope Index,ā such as
Envelope Index
or Envelope Index-shm
.
Code:
andy@iMac ~ % cd /Users/andy/Library/Mail/V8/MailData
andy@iMac MailData % ls -alh Envelope*
-rw-r--r--@ 1 andy staff 201M 12 Oct 10:41 Envelope Index
-rw-r--r--@ 1 andy staff 32K 12 Oct 07:53 Envelope Index-shm
-rw-r--r--@ 1 andy staff 3.5M 12 Oct 10:42 Envelope Index-wal
-rw-r--r--@ 1 andy staff 384K 12 Oct 07:53 Envelope Index..tmp.V6Gcqc-shm
-rw-r--r--@ 1 andy staff 0B 12 Oct 07:53 Envelope Index..tmp.V6Gcqc-wal
andy@iMac MailData %
Tips: Before you delete the files, it makes sense to copy them to a folder on your desktop.
- Launch Mail, and the app will build new Envelope Index files -- this can take a long time if there are numerous messages to go through.
Tips: If everything seems to be working correctly, you can now delete the copies of the "Envelope Index" files from your desktop.
