Restore Litigation Hold settings

To restore Litigation Hold settings, follow these steps:

  1. Open Exchange Management Shell, and connect to your on-premises Exchange Server 2013 deployment.

  2. To restore a user’s Litigation Hold duration setting, run the following command:

     Set-Mailbox <user> -LitigationHoldDuration <valueInDays>

    For example, to set NinaT’s Litigation Hold duration to 90 days, run the following command:

     Set-Mailbox NinaT -LitigationHoldDuration 90

  3. Repeat step 2 for each user whose Litigation Hold duration setting you want to restore.

In an Exchange Online deployment with on-premises Lync Server 2013, and is running the Windows Azure Active Directory Sync tool with hybrid enabled

To restore the Litigation Hold duration setting, follow these steps:

  1. Connect to Exchange Online by using remote PowerShell. For more info, go to Connect to Exchange Online Using Remote PowerShell(https://technet.microsoft.com/en-us/library/jj984289(v=exchg.150).aspx)

    .

  2. To restore a user’s Litigation Hold duration setting, run the following command:

     Set-Mailbox <user> -LitigationHoldDuration <valueInDays>

    For example, to set NinaT’s Litigation Hold duration to 90 days, run the following command:

     Set-Mailbox NinaT -LitigationHoldDuration 90

  3. Repeat step 2 for each user whose Litigation Hold duration setting you want to restore.

After the next time that directory synchronization runs, the Lync 2013 server will pick up the restored Litigation Hold duration settings.
