Exchange 2013 – How to grant permissions for a Group

In this section we will see how we can assign permissions on group in Exchange 2013.

We can assign Send As and Send on Behalf permissions on distribution groups, dynamic distribution groups, and mail-enabled security groups to allow delegates to send messages as a group or on behalf of the group.

Using EAC for Send As and Send on behalf:

  1. Navigate to Recipients > Groups
  2. Select the group for which you need to provide the access and then click edit.
  3. On the properties page, click Group Delegation as shown below:

Using PS commands:

Add-ADPermission -Identity “Service Desk” -User “Helpdesk” -ExtendedRights “Send As”

Remove-ADPermission -Identity "Service Desk" -User MSExchangeGuru/Groups/Helpdesk -ExtendedRights "Send As"
Set-DistributionGroup -Identity "Service Desk" -GrantSendOnBehalfTo James
Set- DistributionGroup -Identity "Service Desk" –GrantSendOnBehalfTo @{remove="James"}

To verify if you have assigned the permissions successfully:

Using EAC for Group Delegation in Exchange 2013:

  1. Navigate to Recipients > Groups > Edit > Group delegation.

Using PS commands:

Get-ADPermission –Identity “Service desk” -User John

Get-DistributionGroup -Identity ServiceDesk | FL GrantSendOnBehalfTo

If you are using Exchange Online Use the below command:

Add-RecipientPermission -Identity Org1@MSExchangeGuru.Local -Trustee “John” -AccessRights SendAs

Remove-RecipientPermission -Identity “Org1” -Trustee John@ MSEXchangeGuru.Local ExtendedRights SendAs

Get-RecipientPermission -Identity Org1 -Trustee John

NOTE: If you want to assign permissions for dynamic distribution groups, please replace distribution group with Dynamic Distribution Group.
Set-DynamicDistributionGroup -Identity "Org1" -GrantSendOnBehalfTo John

    is it possible to add distributiongroups instead of users? So to have a larger group of people added at once.

    i.e. Add-ADPermission -Identity “Service Desk” -distributiongroup “whatever” -ExtendedRights “Send As”

    sorry for the uneducated question I’m on a bit of a schedule.

    Distribution group will not work. you have to run the same command for every user.
