I recently migrated a mail enabled public folder to a standard mailbox.
The mailbox receives email fine from all users except for people who have the email address in their autocomplete from when it was a public folder.
The email just bounces back saying invalid email address
If I delete that address from a users Autocomplete list, the user can email the mailbox without issue.
Is there a way I can bulk delete this email address from all users Autocomplete without having to delete all their Autocomplete email addresses?
