Often there is a requirement to search for Contacts in Archive Manager yet there is not option to specify 'Contacts only' in the Archive Manager website.
There are a few options to complete a request like this:
1 - When creating a new contact the "Full Name" field is what Archive Manager uses as the "Subject" in the Archive Manager database, a 'Subject only' search for whatever is in the Full Name field of the contact should return the results you would like.
2 - Use Recovery Manager for Exchange - Archive Manager Edition to perform this search accross all mailboxes in the archive. This video will demonstrate how to add Archive Manager mailboxes to Recovery Manager for Exchange and once added you can then search based on Message Class (in this case IPM.Contact) .
Here is the info on how to get RME-AM Edition:
Important Note: For a limited time, Archive Manager customers are entitled to Recovery Manager for Exchange – Archive Manager Edition at no additional cost, but you must swap your existing licenses to the new Archive Manager for Email Discovery/Recovery Pack. This must be done by March 31, 2012. Note that the swap may only be performed on perpetual licenses and must be current on maintenance.
Begin the license swap process by visiting https://support.quest.com/Products/ProductSwap.aspx and expand the Windows arrow. If you are not already registered for our support portal, be sure to do so and sign-in before beginning the license swap process. If you have any questions regarding the program, please contact your Quest account manager. If you need assistance locating your Quest account manager, please visit the Contact Us page on our website.
3 - Although direct SQL queries are not supported by Quest Support, you can find this information directly in the database by logging on via SQL Server Management Studio and running:
select * from message where messageclass = 'IPM.Contact' and Subject like '%words in Full Name field%'
If you would then like to see what mailboxes this contact is linked to you can use the MessageID from the above query in this one:
select * from mailboxMessage where messageid = xxxx
use all of the mailbox ID's shown here in the next query:
select name from mailbox where mailboxid in (5,10,15,20,25,30)
This will then give you a list of mailbox names where this Contact is linked.
