I know I can go in and see what policy is applied to the mailboxes by doing the below: 1. Open theExchange Management Console windows. 2. Navigate to theOrganization Configuration and click Mailbox. 3. Select the retention policy in the Retention Policies tab. 4. ChooseMailboxes tab in the Properties. 5. Now we can see the mailboxes which the retention policy applies. But...How would you export that list or do the same in powershell? I need to get a list of what mailboxes are in a certain retention policy. I tried different formats of get-mailboxstatistics but I never can get the retentionpolicy field to return any results. Also need to find what mailboxes do not have a retention policy applied. Thanks for your time.

which version of exchange you are running for exchange 2010 you can use Get-RetentionPolicy -Identity "policy name" | Format-List

Exchange 2010 SP2 That command didn't get the list of what mailboxes are in that particular policy, it only returned and populated the below fields: RunspaceId : RetentionId : RetentionPolicyTagLinks : AdminDisplayName : ExchangeVersion : Name : DistinguishedName : Identity : Guid : ObjectCategory : ObjectClass : WhenChanged : WhenCreated : WhenChangedUTC : WhenCreatedUTC : OrganizationId : OriginatingServer : IsValid :

I got what I needed by using the filters in the recipient configuration. Thanks.
