In and Sent mail missing how to recover?

Running latest version of Snow Leopard. Switched over to iCloud before the drop dead date. All has been fine until this morning when my In and Sent boxes were empty of all messages. Archived and mail moved to other folders remain.

Rebuild remains greyed out. Take accounts offline and online is also greyed out.

Time Machine from last night's final backup displays the messages, but after two tries the restore function does not seem to restore the In or Sent box messages. All messages are on the server and on my iPhone and iPad and all appear in Time Machine. I just can't get them to restore.

Outgoing Mail Server is smtp.me.com.my name

How do I get mail in Snow Leopard to start playing nice with iCloud again and resync my In and Sent folders?
