Hi,

We have recently leveraged Litigation Hold and unlimited mailbox sizes in lieu of GFI MailboxArchiver.

Our user accounts admin just deleted an AD user including the mailbox in ADUC and watched it as it vanished (refresh button) in EAC.

As far as I know the mailbox should still be on the exchange server, how can I verify that? My aim is to make sure the mailbox has not been permanently deleted since we are required to maintain it for 7 years.

I have rewritten the process for the user admins, they should Disable user in ADUC, Disconnect Mailbox, Delete user in ADUC, is that the right way to delete the user but maintain the mailbox for 7 years? Command used: Get-Mailbox -ResultSize Unlimited -Filter {RecipientTypeDetails -eq "UserMailbox"} | Set-Mailbox -LitigationHoldEnabled $true -LitigationHoldDuration 2555

Tnx,

Timotatty

Hi,

Generally, disabled and deleted mailboxes are retained in the mailbox database until the deleted mailbox retention period expires, which is 30 days by default. After the retention period expires, the mailbox is permanently deleted or purged.

If the mailbox is still retained in database, we can run the following command to list all deleted or disabled mailbox:

Get-MailboxDatabase | Get-MailboxStatistics | where {$_.disconnectdate ne $null} | FL displayname,MailboxGUID,DisconnectReason,DisconnectDate

If you want to retain the mailbox for 7 years, please make sure the mailbox retention period has been set for 7 years. We can run the following command to check it:

Get-MailboxDatabase | fl Identity,*Retention*

If it is not set to 7 years, we can run the following command to set it:

Get-MailboxDatabase | Set-MailboxDatabase -MailboxRetention dd.hh:mm:ss

Hi Winnie,

It seems like your suggestion works. But still, something is unclear:

Litigation hold is on so why do I still need to increase the retention time to 7 years? I would have thought that is automatically would be retained. What am I missing?

Tnx,

Tim
