Hi, I created a backup of my Thunderbird profile including various email accounts and calendar. I used the build in export function of Thunderbird to create this backup. Unfortunately the file is slightly bigger than 2GB. I had a severe copmputer crash now and I wanted to import the backup. It turns out that the zip-achive is damaged. I cannot unpack it with any zip-software and also repairing the archive with winrar did not work. Is there any chance that I can at least restore some of the information? Best, Robert
