Any way to get rid of this. Ive tried to fix it for some time but still pops up. FYI: I do NOT want to use mbox The reported error was "Failed to append to mbox:///home/frosty/.local/share/evolution/mail/local#Sent: Invalid folder URI 'mbox:///home/frosty/.local/share/evolution/mail/local#Sent' Appending to local 'Sent' folder instead.". Thanks John
