Use the Offline Folders tabbed section
to specify your offline folders. When you switch from online mode to offline
mode, Evolution
creates copies of the folders you
select, on your system. For more information on offline mode and online mode,
see Working Offline.
Use the mail folder tree to select the folders that you want to work with offline. Click on the plus sign (+) beside a folder to expand the contents of the folder. To collapse the contents of a folder, click on the minus sign (-) beside the folder.
