I have a user currently using Thunderbird version 18.104.22.168 (20061025). She made a change in her columns to display settings and cannot change them back. I am attempting to have the columns for the Sent folder show only Recipient and not sender, but not have the Inbox folder change. I am able to do this fine on other workstations that have Thunderbird, but not on hers. When I make add recipient to her Sent folder, it adds to the Inbox also.
Any help would be great!
