Email in Exchange inbox disappear in Mail

I have a slightly different problem. Mail syncs with Exchange fine and I have not experienced the changed mail server issues the others have been experiencing. However, once in a while, the mail from my Exchange inbox would all disappear from Mail as if the whole Inbox is empty (save for emails from other servers like Gmail, iCloud). Originally, I thought it was a sync problem so I deleted the account and then set it up again and waited painfully for everything to sync back in. However, this phenomenom still happened randomly once in a while. This time, I just close the Mail program and restart it and then everything is back to normal.

While this is a workaround, it is nevertheless very annoying. Has anyone else experienced this with Mail and Exchange server 2007? Any ideas how this can be fixed? Thanks.
