Hello, I have filters that divide up the incoming emails to individual input folders within the local folder by recipient. From there I manually review the mail and further store emails into local folders based on the sender. Today, I tried to move an email into a local folder, and got some kind of space error, that suggested I start deleting old emails. WTF!!! No. I HAVE HUNDRED OF GIGS OF FREE SPACE ON MY HARD DRIVE. How do I expand the allowable space that Thunderbird can use? Where is that option? Thanks Everybody.
