Use the Start-MailboxSearch cmdlet to restart or resume a mailbox search that's been stopped.

When restarting a search, any previous results returned by the same search are removed. To preserve previous search results and resume the search from the point it was stopped, use the Resume switch.

Start-MailboxSearch -Identity <SearchObjectIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-Force <SwitchParameter>] [-Resume <SwitchParameter>] [-WhatIf [<SwitchParameter>]]

You can use Multi-Mailbox Search to search one or more specified mailboxes or all mailboxes across the Microsoft Exchange Server 2010 organization. A search is created by using the New-MailboxSearch cmdlet or the Web management interface for Microsoft Office Outlook Web App.

To learn more about Multi-Mailbox Search, see Understanding Multi-Mailbox Search.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Multi-Mailbox Search" entry in the Messaging Policy and Compliance Permissions topic.


Parameter Required Type Description




The Identity parameter specifies the name of the search. The name is referenced when starting, stopping, or removing the search.




The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch.




The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.




The Force switch suppresses the confirmation prompt displayed before the command is executed.




The Resume switch resumes a stopped, failed, or partially succeeded search from the point it stopped. If you use the Resume switch to resume a search, previous search results aren't removed from the target mailbox.




The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch.
