Mail on macOS Sonoma quits unexpectedly after opening the app

Created as it is not possible to post a reply in "Apple Mail quits unexpectedly after opening in Sonoma".


After identifying the culprit mail box using System Settings / Internet account, found a recent (of course) suspect mail that was indeed a spam message.

Removed it with the correspondant mail box Web mail, and that's it.


Now the issue is gone.

 Remove and reindex envelope files

Mail uses an envelope index to catalog and search message headers; these can become defective and cause Apple Mail not to work.

How to manually remove envelope files:

  1. Quit Mail and open the Finder.
  2. Holding down the Option key from the top menu, select Go > Library.
  3. Now, select Mail > V9 folder (depending on your macOS, this could be another number).
  4. Now, select the MailData and locate the following files:
  5. Envelope Index-shm
  6. Envelope Index-wal
  7. Envelope Index
  8. Copy and paste them on your desktop, deleting the original files in MailData. Then, reopen Mail and test.
