Rated 5 out of 5 stars
Since the Thunderbird search function (search box) does not recognize the "display name" from the address book, is there a chance for you to get this fixed ?
E-Mail Address: firstname.lastname@example.org
Display Name: John Doe
If you search e. g. for "John" via the Thunderbird searchbox, you will get no results. Only if search e. g. for test.
