I am moving from a won 7 laptop to a surface pro 3. I copied the thunderbird account per the mozilla video instructions (<user>appdata/roaming folder). I copied my 5 gb file over and then started up. Then the email doesn't work. It won't connect to my server. I also only get a handful of emails showing up and they are from 2007. I should have them up to last week. Thunderbird was just downloaded on a fresh install of Win 10 on the tablet. It's up to date. I checked that there is only one profile in the profile folder. I also checked that the only profile in the profile configuration file is the same as the profile folder. Everything looks correct. Any additional troubleshooting thoughts I can attempt?
