In a Microsoft Exchange Server 2013 environment, you try to use eDiscovery through the Exchange Administration Center (EAC) to search all mailboxes or some distribution groups. If you have the "Search All Mailboxes" check box selected, the search fails and the following exception is generated:

InfoWorker.Common Search MailboxSearchServer.Start error System.ArgumentNullException: Value cannot be null.

----- ----- at Microsoft.Exchange.EDiscovery.MailboxSearch.MailboxSearchServer.AddSearchToWorkItemQueue(SearchId searchId String ownerId)"


This problem occurs when the Mailcontact or Mailuser objects are contained in the search query.


To fix this problem, install Cumulative Update 12 for Exchange Server 2013 or a later cumulative update for Exchange Server 2013.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
