My Sent mailbox in Mail is only showing the most recent 8 items I've sent (though all my previous items are on the server as seen in webmail). It's displaying a small warning next to it:
And when I click the <!>, I get the following error.
The Sent mailbox could not be created on the mail server. The local "Sent Messages (MobileMe)" mailbox was created instead. Mail has changed your account's Mailbox Behavious preferences to use the local "Sent Messages (MobileMe)" mailbox.
Any ideas? And I don't see a new local Sent mailbox.
