Locked out of Folder in Thunderbird - message given that folder is FULL.
I have just migrated Thunderbird from PC to my first Mac. I have two sub,sub,sub,sub folders under LOCAL FOLDERS that are both showing empty when I click on them. However these folders had data when they were migrated and that data still exists on my old PC.
Complication: I tried to save data to both of these sub folders to check the reaction. The following is a typical message I received from the system: "folder 'Building Standards Dept' is FULL, and can't hold any more messages. To make room for more messages, delete any old or unwanted mail and compact the folder." Problem 1: The data is precious and I don't want to delete it. Problem 2: This seems like "catch 22" in that I'm told that I need to delete files to make room for new files but I'm unable to get access to delete anything. NOTE: There is not a lot of files inside these sub folders. Your assistance would be appreciated - thanks.
