Hello,

I need to pull a report of all deleted mailboxes (users) that have Litigation Hold enabled. I'm not sure the exact state of these mailboxes; deleted, inactive, stale...These mailboxes are "floating" in the cloud and I cannot see them, but are available for eDiscovery. The 365 reports available online are not very useful for this.

I tried "Get-Mailbox -SoftDeletedMailbox" but I'm not sure if this gives me the mailboxes that were deleted over 30 days.

Any idea how I can get the correct inform

Hi aburica,

This question was posted in Office forum but the request is related to Exchange Mailbox, so I have moved this thread to Exchange forum to let you get more appropriate support.

Hi,

As you mentioned,  the soft-deleted mailbox retention period in Exchange Online is 30 days. This means that the mailbox can be recovered within 30 days of being soft-deleted. After 30 days, a soft-deleted mailbox is marked for permanent deletion and can't be recovered. 
More details about Remove a hold from an inactive mailbox in Exchange Online, for you reference:

First of all, thank you Melon Chen for moving my post in the proper forum.

Second, Thank you Allen for your response. I believe I found what I was looking for. Before you posted the link, I was running:

$InactiveMBs = get-mailbox -ResultSize unlimited -InactiveMailboxOnly
$InactiveMBs | select PrimarySmtpAddress,LitigationHoldDate | sort LitigationHoldDate

I wasn't 100% sure that was what I was looking for, but I get the same result with:

Get-Mailbox -InactiveMailboxOnly | FL DisplayName,Name,IsInactiveMailbox,LitigationHoldEnabled,InPlaceHolds

Thanks for your help...I have a better understanding now.
