Upon finishing setup of Thunderbird for my work email addresses (IMAP on a server here in the building) I am getting all of my emails, but they are all marked as read any time I close and re-open the program. If I keep Thunderbird open it will push them through as unread until I open them as you would expect it to do normally. I've experienced this on both a Spectre and a Thinkpad, so I don't believe it's the machine. The only thing these have in common that my others do not is that I have let the client automatically detect the settings on these two machines and on the others I copied over any settings along with the logins, like port or what have you. I'm not a network guy. I haven't yet had time to delete the accounts and try setting them up individually, because by the time I open this and remember I'm already working. I'm hoping there's just something I can uncheck somewhere, because I use different machines for different purposes and accounts and having everything marked as read all the time is a problem. Thank you!
