List Litigation Hold & eDiscovery Hold For a List of Inactive Mailboxes

There are six types of holds that can be applied to an Inactive mailbox. You need to PowerShell to determine the type of hold. See Change the hold duration for an inactive mailbox | Microsoft Learn

Step 1 in this article shows you how to collect/report on this data, the only difference when it comes to inactive mailboxes is that you have to include the corresponding switch. https://learn.microsoft.com/en-us/purview/ediscovery-delete-items-in-the-recoverable-items-folder-of-mailboxes-on-hold?view=o365-worldwide#step-1-collect-information-about-the-mailbox

Another option is to use the Invoke-HoldRemovalAction cmdlet, which can be used to both report on or remove specific holds: https://www.michev.info/blog/post/5792/how-to-use-the-invoke-holdremovalaction-cmdlet-to-remove-legacy-and-orphaned-holds-in-microsoft-365 

Hi chrishorsted720,

This is likely possible only via powershell. You can use the following commands to get the required details,

1. Litigation hold details are properties of Get-Mailbox command
2. Case hold details can be retrieved using Get-CaseHoldPolicy

Refer to:

Get-CaseHoldPolicy (ExchangePowerShell) | Microsoft Learn

Hope this helps!
