Apple Mail

Thank you for your assistance. I did both of your suggestions. Reinstalling the OS did not fix it, however, I set up a guest user and then they set up their email account through Apple Mail while logged in as a guest. The email that they deleted DID go to the trash folder. So, my problem is evidently isolated to my user/admin account. Now what?

You can try (moving to trash) deleting the associated com.apple.mail.plist

Quite Mail.app

From the Finder >Go>Got to folder copy and paste:

~/Library/Containers/com.apple.mail/Data/Library/Preferences

delete the com.apple.mail.plist

relaunch the mail.app and compare your results; plist are rebuilt on relaunch of the application.

If no resolve—

you can always from the the trash Control click the com.apple.mail.plist >Put back

Call Customer Support  (800) MY–APPLE (800–692–7753)

or on line  Apple Support

P.S. On "double check the location"...."deleted messages" is not an option! I've attached a screen shot of my options. Should I do something there before I try the new suggestions that you sent? Thanks!

Well, if you don't have it you don't have it as an option‚ I can not explain that part...

I 'suspect' it is checked correctly.

I would go ahead and try rebuilding the plist by deleting the old one and compare your results.

just for your amusement, this is what I have on my main account :

My Apple Mail suddenly stopped putting deleted emails in the trash. They are just entirely deleted. I checked the preferences in mail, and it shows that items in trash are never to be deleted.

I tried removing my email account and then adding it back. That didn't work.

I tried booting up in safe mode and the problem still existed. I even tried removing my mail account and adding it back in safe mode. That didn't work.

I temporarily installed another mail app (Mailspring) to see if it would have the same problem, but it didn't. All deleted emails went to the trash folder. That proves that it's a problem with Apple Mail, not the server. I called Apple Support, and they don't have any answers for me. I'm hoping that someone out there in Cyberspace does! I'm running Monterey 12.6.

Hmmm....

A guest account is another test to trouble shoot further:

Test issue in another user (or guest user) account Set up users, guests, and groups on Mac - Apple Support

This will tell you if it a universal issue or isolated to your user/admin account.

I would not hesitate to reinstall the macOS on top of your existing macOS and compare your results

Besides your "never" I would also double check the location, make a change and come back to the default to test:
