Sharing Local Folder in Mozilla

Is there a way to share my Local folders for Mozilla Mail. My Suse 9.0 is Mozilla 1.4 and Win2k Pro is Mozilla 1.5. I've set it so that the Local Folders are on a FAT32 Partition but as far as I can see, there is no way to import the settings/local folders between the two different Mails. Am I missing something?
