 ## SYNOPSIS
 This cmdlet is available in on-premises Exchange and in the cloud-based service. Some parameters and settings may be exclusive to one environment or the other.
 
-On July 1, 2018, you'll no longer be able to use the New-MailboxSearch cmdlet to create In-Place eDiscovery searches and In-Place Holds in Exchange Online. To create eDiscovery searches and eDiscovery case holds, please start using New-ComplianceSearch and New-CaseHoldPolicy in the Security & Compliance Center. You'll still be able to use Set-MailboxSearch to modify existing In-Place eDiscovery searches and In-Place Holds. Creating new searches and holds in Exchange Server 2013 will still be supported, and searches run from your on-premises organization in an Exchange hybrid deployment aren't affected by this change.
-
 Use the New-MailboxSearch cmdlet to create a mailbox search and either get an estimate of search results, place search results on In-Place Hold or copy them to a Discovery mailbox. You can also place all contents in a mailbox on hold by not specifying a search query, which accomplishes similar results as Litigation Hold.
 
-By default, mailbox searches are performed across all Exchange 2013 or later Mailbox servers in an Exchange organization, unless you constrain the search to fewer mailboxes by using the SourceMailboxes parameter. To search mailboxes on Exchange 2010 Mailbox servers, run the command on an Exchange 2010 server.
