PLEASE HELP ME!!  I may have lost 900 contacts and all the associated information!!  I just tried to open my contacts (as well as my calendar) and neither one will open, although my e-mail and folders are showing in MS Outlook 2007!  I am running Windows Vista Home Premium.  When I click on Contacts within Outlook, I get the following message:  The messaging interface has returned an unknown error.  WHAT CAN I DO??

Try to use the Inbox repair tool to scan and fix errors in the Outlook data file in use.

Note: back-up the Outlook Data File (PST) before repair.
