Close Mail if it is open. Then in your Mac, on finder, Hold down Option key on your Keyboard, click on Go menu and select Library. This will take you to the Library folder of your User Account. Open Mail folder, open V2, open MailData, delete any file that begins with “Envelope Index,” such as Envelope Index or Envelope Index-shm. Restart Mail
If that didn't work, then again hold down Option key on your Keyboard, click on Go menu and select Library. Trash the Mail folder. Restart Mail (Don't empty the trash)
Let me know if that didn't work, so we can continue troubleshooting. Don't Rate my answer until you are satisfied
Where can I find the "Go Menu" key?
Could find no Envelope Index in Library.
And did not see a "mail folder" although I did see other references to mail in the library.
