'''Hello''' from Sweden, and I'm sorry if any grammar or expression is incorrect. All of a sudden login credentials is asked for (see attached image), for an '''old''' account that I've already (a couple of weeks ago) deleted ''both'' in Thunderbird and ''also'' on the server (on sethpylad.se). I always click the Cancel button when this comes up, but I don't understand this at all because when I try to send an email to the '''existing''' new account on the same server it all works as it should? So it seems like it only ask for credentials for the old/deleted account? Is there any way I can change any setting to not be annoyed by this from here on? I'm using a HP laptop. And on my desktop computer I can't really recall having this problem at all. '''Edit:''' I just deleted an Address Book that was associated with that old account, but the problem prevails. '''/edit''' Thanx in advance! ''Seth Pylad from Sweden''
