I've tried:

If Cocktail was used prior to this issueâ I would be highly suspect this may have lead to the issue to begin with.
Cocktail has been known to cause problems running script.

One afterthoughtâ try remove the mail container.
Quit mail.
Finder>Go>Go to Folder, copy & Paste:
~/Library/Containers/com.apple.mail
Highlight all the contents.
Then right-click and choose "New Folder with Selectionâ. Do not move the new folder from this current location.
You can close the Finder window.
The next step will be to restart the Mac and test
