One of my users is having an issue with her mailbox.

She has a folder called "General Old Mail" which has a folder called "People" inside of it. Within the People folder are several folders named after employees here.

Starting today, all may prior to Jan 22 2010 has disappeared from all of the sub-folders of "People".

I have tried searching using a prior to Jan 22 2010 search criteria. This shows mail in all folders but any of General Old Mail >> People sub-folders. I've even checked trash/junk. None of the mail is there, though the size of her mailbox does not seemed to have changed(13.1gb).

Is there any way to find out if the mail is physically gone and perhaps reindex these folders if it is not?

Much obliged to anyone who can help out as this is a lot of her mail.
