If it is a corrupt plist you can try— quit the mail.app
and Delete the com.apple.mail.plist from Finder>Go>Go To Folder, copy and paste:
~/Library/Containers/com.apple.mail/Data/Library/Preferences/com.apple.mail.plist
relaunch the mail.app and test. The plist will automatically rebuild itself.
if no change you can always Control click the deleted .plist in the Trash>Put Back
------------------------------------------
If no resolve—
Quit mail.
From the Finder>Go>Go to Folder, copy & Paste:
~/Library/Containers/com.apple.mail
Highlight all the contents in this folder. Place your mouse on the selection,
Then Control click (right-click) and choose "New Folder with Selection”. 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
After the computer is restarted, open the Mail.app> Preferences to see if it opens properly.
