When I click on my junkmail folder, I get a message that reads:There is a problem with the Office database. To use the database, you must rebuild it using the Database Utility. It then goes on to describe what the Office database is for. Once this message comes up, Outlook freezes (beach ball spinning). It gives me the choice to either cancel or rebuild. If I click "cancel" it closes Outlook completely. I haven't clicked "rebuild."

This only happens when I open the junkmail folder, otherwise Outlook appears to be operating normally. I'm concerned that one of the three emails in the folder is perhaps a virus?

Edit: just noticed that a block of time has disappeared from outlook meaning that emails that were received and responded to yesterday afternoon have completely disappeared from my system.

I'm using Outlook for Mac 2011, version 14.3.1

Thanks!
