I disabled my POP account and created an IMAP account with the same information. The folders and emails transferred well enough but in the inbox they all came in as READ when I had 509 that were UNREAD in the POP version. Also, the color coding of the tags was missing. If I copy the originals manually to the new IMAP account they transfer with tags and as unread, but then I have to go through and delete duplicates. In some of my other folders this wasn't a problem. In some it was. There seems to be no rhyme nor reason for it. Does anyone have any idea why this happened? I am using version 45.1.1 of Thunderbird.
