Get-DistributionGroup - Restricted Groups - AcceptsMessagesOnlyFrom*

If there anything to explain as how one can get the restricted distribution groups with easily readable property containing a string of users, below would be the script for you. Try :)


Get-DistributionGroup -ResultSize Unlimited | where{$_.AcceptMessagesOnlyFromSendersOrMembers -ne $null} | select Name,@{Name="AcceptMessagesOnlyFromSendersOrMembers";Expression={[string]::join(";",($_.AcceptMessagesOnlyFromSendersOrMembers| foreach {$_.name }) )}},@{Name="AcceptMessagesOnlyFrom";Expression={[string]::join(";",($_.AcceptMessagesOnlyFrom| foreach {$_.name }) )}},@{Name="AcceptMessagesOnlyFromDLMembers";Expression={[string]::join(";",($_.AcceptMessagesOnlyFromDLMembers| foreach {$_.name }) )}},DisplayName,SamAccountName,PrimarySmtpAddress,OrganizationalUnit,@{n="EmailAddresses";e={$_.EmailAddresses}},@{Name="ManagedBy";Expression={[string]::join(";",($_.ManagedBy | foreach {$_.name }) )}},GroupType | Export-Csv C:\RestrictedDLsReport.csv -NoTypeInformation

Add / Remove user in BookInPolicy / ResourceDelegate - Exchange 2013

Add / Remove user in BookInPolicy / ResourceDelegate - Exchange 2013 powershell

When we create a function of ResourceDelegate, below will be the effect:

#user gets added to calendar folder with access permissions as {Editor}

#user gets added to ResourceDelegates and not in BookInPolicy.

To add Calendar Resource Delegate we can use below function which creates a cmdlet ‘Add-CalendarResourceDelegate’ in powershell:

function Add-CalendarResourceDelegate {

Param(
$RoomName
, $newDelegate
)
$resourceDelegates = (Get-CalendarProcessing -Identity $RoomName).ResourceDelegates
$resourceDelegates += $newDelegate
Set-CalendarProcessing -Identity $RoomName -ResourceDelegates $resourceDelegates
}

CMD syntax:

Add-CalendarResourceDelegate -Identity $Roomname "MeetingRoom@Test.com" -newDelegate UserID9

To Remove All Users from ResourceDelegate:

Set-CalendarProcessing -Identity "MeetingRoom@Test.com" -ResourceDelegates $null

  

===========================================================

When we use function of Bookinpolicy below will be the effect:

#user gets added to bookinpolicy and current users will be retained.
#user gets added to calendar folder with access permissions as {LimitedDetails}

To add user in Calendar BookIn Policy we can use below function which creates a ‘Add-CalendarBookInPolicy’ cmdlet in powershell:

function Add-CalendarBookInPolicy {

Param(
$roomName
, $newUser
)
$bookInPolicy = (Get-CalendarProcessing -Identity $roomName).BookInPolicy
$bookInPolicy += $newUser
Set-CalendarProcessing -Identity $roomName -BookInPolicy $bookInPolicy
}

CMD syntax:

Add-CalendarBookInPolicy -Identity $Roomname "MeetingRoom@Test.com" -newUser UserID

To Remove All Users from BookinPolicy:

Set-CalendarProcessing -Identity "MeetingRoom@Test.com"  -BookInPolicy $Nul

To Remove Single User from ResourceDelegate:
function Remove-CalendarResourceDelegate {

Param(

$roomName

, $delegateToRemove

)

$resourceDelegates = (Get-CalendarProcessing -Identity $roomName).ResourceDelegates

$delegateToRemoveIdentity = (Get-Mailbox $delegateToRemove).Identity

$resourceDelegates.Remove($delegateToRemoveIdentity)

Set-CalendarProcessing -Identity $roomName -ResourceDelegates $resourceDelegates

}

#CMD syntax:

Remove-CalendarResourceDelegate -roomName “MeetingRooms@Test.com” -delegateToRemove User1

Note: Custom functions/cmdlet are only available until the current session is active. Next time when you start EMS, again we have to create function/cmdlet. To make it persistent need to write some other codes.
