Can you only configure Send As permissions on Mail Universal Security groups?

Or are you also able to set Send As permissions on Mail Universal Distribution Groups?

Are you trying to Send As the email address of the group? Or are you trying to put people in to a group, and use that group to assign Send As permissions to another mailbox? – longneck Jan 7 '13 at 20:28
Send As the email address of the group – PnP Jan 7 '13 at 20:29

You can send as either a Mail Distribution Group or a Mail Security Group. However, the commands to give these permissions are different.

For a Mail Distribution Group:

Add-RecipientPermission <group> -AccessRights sendas -Trustee <user>

For a Mail Security Group:

Add-ADPermission <group> -ExtendedRights "send-as" -user <user>

I think this is being made way more complex that it needs to be - my question was - Does your Distribution Group have to be a Mail Enabled Security Group (and NOT a normal Disitribution Group) in order to assign Send As rights to a user. – PnP Jan 7 '13 at 21:05
Or can you assign a Distribution Group (which is not a Security group) and give Send As Permissions to a user – PnP Jan 7 '13 at 21:06
Even if my initial revision had a poorly worded first sentence, the fact that I showed how to assign permissions so a user can send as a group should have given it away: both types support the ability for users to send-as that group. – longneck Jan 7 '13 at 21:12
Well Add-RecipientPermission applies only to Exchange Online – PnP Jan 7 '13 at 21:15
Actually Add-RecipientPermission applies to OnPrem as well. – Nate Jan 8 '13 at 15:07
