To configure a Dynamic Distribution Group in Exchange 2010, you can do it in two ways: 1. From EMC in Recipient Configuration > Distribution Group, right click on a existing Dynamic Distribution Group and select Properties. Go to Filter and Conditions tabs and select the appropriate settings. 2. From EMS you will only find a few conditions/filters that you can choose from in the GUI. So you will have to use EMS to fine tune your DDG. For example, if you want to filter the members of a Dynamic Distribution Group by city, you can use it to query users that have the City attribute assigned. To change the existing Dynamic Distribution Group which uses LDAP filter to use OPATH filter you use:

Set-DynamicDistributionGroup -Identity "GROUPNAME" -RecipientFilter {(Alias -ne $null -and City -like 'Bucharest') -and -not(Name -like 'SystemMailbox{*') -and -not(Name -like 'CAS_{*')}

All the users that have Bucharest as the City attribute will be members of this Distribution Group.

You can export a mailbox in Exchange 2010 SP1 with a new method called Mailbox Export Requests instead of previous Export-Mailbox command.

New-MailboxExportRequest -Mailbox mihai.caltaru -FilePath \\network_share\mihai.caltaru.pst

If you don't want to export it locally, you need to configure the network share in which the permissions for Exchange Trusted Subsystem are set to read/write. Pipe Get-MailboxExportRequest into the Get-MailboxExportRequestStatistics cmdlet and you will get detailed information regarding your export. When it finishes, the request remains on the server until removed by an administrator using Remove-MailboxExportRequest. To clear all your Exchange requests:

Get-MailboxExportRequest | where {$_.status -eq "Completed"} | Remove-MailboxExportRequest
