Hi - I was presented with an update for Thunderbird, without an option to not update. So I updated. But now I've lost all the appointments and recurring dates on my original calendar. I can't find any sort of backup. Nor any synchronisation. This is going to cause me a ton of trouble and extra work. Can this be rectified? I have a basic knowledge of email so any technical stuff will need to be done by you. I really hope you can help. oh and please don't redirect me to some webpage which offers generic help. I need some hands on help please Kind regards Paul
