Yesterday, while I was out of the office, I receive multiple emails from my users stating their contacts disappeared. I have looked through everything I can find and cannot figure out why they disappeared. This did not happened to everyone, about 1/2 of the staff experienced loss.
After beating my head against the desk, I finally decided to restore the contacts from a backup. Unfortunately, the only backups I have are database level. I managed to get the database and save it to the exchange server's hard drive. I have now opened the New Mailbox Database wizard and was going to add this database to Exchange so I could pull the contacts.
My question is, if I attach this new database to the existing storage group (1st storage group) will it replace the existing database or will just add to the data and the contacts begin to repopulate?
