Assistance Required with Powershell command to modify Dynamic Distribution Group - Exchange 2010

Hi There,

I am needing to add to this existing dynamic distribution group an additional filter. The filter is to exclude from this group exchange mailboxes that have been selected to be hidden from address lists. I believe filter to add is this: -and -not(HiddenfromAddresslistsEnabled -eq $true)

However I am running into an issue when adding in this filter as nothing is being accepted in powershell when trying to modify the filter. Can someone please assist with letting me know the required command to update the filter to include the new filter "-and -not(HiddenfromAddresslistsEnabled -eq $true)" ?

The current filter is shown below and I have also attached a screen capture.

((((((RecipientType -eq 'UserMailbox') -and (-not(Name -like 'Belton IT')))) -and (-not(Name -like 'support')))) -and (-not(Name -like 'SystemMailbox{*')) -and (-not(Name -like 'CAS_{*')) -and (-not(RecipientTypeDetailsValue -eq 'MailboxPlan')) -and (-not(RecipientTypeDetailsValue -eq 'DiscoveryMailbox')) -and (-not(RecipientTypeDetailsValue -eq 'ArbitrationMailbox')))

Try this to get the old filter and append the new filter text and set the group with the new filter.

$grp = Get-DynamicDistributionGroup "group name"
$filter = $grp.RecipientFilter
$newfilter = " -and -not(HiddenfromAddresslistsEnabled -eq $true)"
$newstr = "$filter $newfilter"
Set-DynamicDistributionGroup "group name" -RecipientFilter $newstr

Run this command first to get the recipient filter value for your dynamic distribution group (DDG)...

Get-DynamicDistributionGroup -Identity "DDG_NAME" | fl Name,RecipientFilter

Open in new window


The result should return something similar to this currently set for the filter...

((((CustomAttribute1 -eq 'TestDDG') -and (Alias -ne $null))) -and (-not(Name -like 'SystemMailbox{*')) -and (-not(Name -like 'CAS_{*')) -and (-not(RecipientTypeDetailsValue -eq 'MailboxPlan')) -and (-not(RecipientTypeDetailsValue -eq 'DiscoveryMailbox')) -and (-not(RecipientTypeDetailsValue -eq 'ArbitrationMailbox')))

Open in new window


Before the last parentheses, I added " -and (-not(HiddenFromAddressListsEnabled -eq 'True'))" to format the value that will make up the updated filter...

{((((CustomAttribute1 -eq 'TestDDG') -and (Alias -ne $null))) -and (-not(Name -like 'SystemMailbox{*')) -and (-not(Name -like 'CAS_{*')) -and (-not(RecipientTypeDetailsValue -eq 'MailboxPlan')) -and (-not(RecipientTypeDetailsValue -eq 'DiscoveryMailbox')) -and (-not(RecipientTypeDetailsValue -eq 'ArbitrationMailbox')) -and (-not(HiddenFromAddressListsEnabled -eq 'True')))}

Open in new window


NOTE: The filter must be encapsulated with the squiggly brackets or an error will occur.  An error will occur even when quotes are used too.

Finally, to update the filter, I ran the command like this.

Set-DynamicDistributionGroup -Identity "DDG_NAME" -RecipientFilter {((((CustomAttribute1 -eq 'TestDDG') -and (Alias -ne $null))) -and (-not(Name -like 'SystemMailbox{*')) -and (-not(Name -like 'CAS_{*')) -and (-not(RecipientTypeDetailsValue -eq 'MailboxPlan')) -and (-not(RecipientTypeDetailsValue -eq 'DiscoveryMailbox')) -and (-not(RecipientTypeDetailsValue -eq 'ArbitrationMailbox')) -and (-not(HiddenFromAddressListsEnabled -eq 'True')))}

Open in new window


Upon completion, verification of the DDG resulted in mailboxes explicitly hidden from the GAL that do not show when previewing from the DDG Filter tab.

P.S. What you are requesting to do only satisfies the admin's preview from the DDG in the Exchange mgmt. console, as the mailboxes that are hidden from the GAL are not visible for users using Outlook or OWA.
