I have a new PC, DL thunderbird and added my 2 email accounts, then i selected the unified account so i can have both accounts emails in the one inbox, however when i first DL the emails, it shows every email twice (and they show in the counter) then when i click on the inbox all the doubles disappear. How can i stop this so i dont have to click the inbox the get the doubles to not be there please? Any assistance would be greatly appreciated.
