Archive command not working Apple Mail in Ventura with Exchange

Hi all,

I recently received a new Mac Studio.

I use Apple Mail to access my Microsoft Exchange account. Unfortunately, I'm not able to use the Archive shortcut (control-command-A) to archive messages because it gives the error message The message “Effort reduction” could not be moved to the mailbox “(null)” (see screenshot below).

I can:

1. Transfer messages that are in my iCloud account to the iCloud Archive successfully with command-control-A.
2. I can manually transfer messages to the Exchange Archive folder by dragging and dropping.
3. I can also transfer messages to the Exchange Archive with the shortcut command-control-6 (I've set up the Exchange Archive) as a shortcut.

I've tried:

1. Rebuilding the Exchange Mailbox.

However, I would really love to use command-control-A. It seems like Mail doesn't know to assign the Exchange Archive to this shortcut, and there is no way to tell it in the new version of Mail.

Is there any advice you might have?

All the best, and many thanks,

-Buz
