Mac Mail 6.2 on OSX 10.8.2 - can't move mail into folders
When I try to move email from one folder to another I get the error message: "The message (subject name) could not be moved to the mailbox (mailbox name). An error occurred while moving messages to mailbox (mailbox name)" and then I can't delete them, move them, change anything about them, they just stay there in that folder??
MacBook Pro, OS X Mountain Lion (10.8.2)
