I'm having a problem synchronizing my folders that have attachments in them. Some (but not all) emails that have attached files are causing the synchronize to fail. If I move these email messages to a non-synchronizing folder, I have no problem synchronizing my folders. However, when I try to move the messages with attachments, I get the following error message,

"Can't move the items. Some items could not be moved. They were either already moved or deleted, or access was denied."

If I keep trying, the emails with attachments will eventually let me move them. If I move those messages back into the original folder, it will then let me synchronize my folders without a problem. It isn't all of the emails with attachments that cause trouble, but I can't tell which of them are causing the problems.

Has anyone else had this problem?
