The In-Place hold
The Exchange 2013 and 2016 release allows admins to create granular hold policies by allowing them to preserve items in the mailbox using the following scenarios:
Indefinite hold: This feature is called Litigation hold in Exchange 2010, and it allows mailbox items to be stored indefinitely. The items in this case are never deleted. It can be used where a group of users are working on some highly sensitive content that might need a review later.
The following example sets the mailbox for Amy Alberts on the Litigation hold (in Exchange 2010) for indefinite hold:
Set-Mailbox -Identity amya -LitigationHoldEnabled $True
In Exchange 2013 and 2016, you will need to use the New-
MailboxSearch
cmdlet without any parameters as shown next to get the same results:New-MailboxSearch "Amy mailbox hold" -SourceMailboxes "amya@contoso.com" -InPlaceHoldEnabled $True
The same can be achieved using the In-place E-discovery and hold wizard in Exchange Admin Center as shown in the following screenshot...
