Error: " You don't have permission to send to Distribution List"

Hello,

User A has full access to a ShareMailbox let's call it abc@xyz.com
User A wants to Send an Email to mail enabled distribution list (123@xyz.com) from: abc@xyz.com / sharedmailbox.

User A's actual email address is added to the delivery management of 123@xzy.com but User A still sees the error " you don't have permission to send to" when she tries to send email to that distribution list.

Things that I have done so far to fix the issue:
- Downloaded the GAL
- Recreated User A's email profile

The issue seems specific to the distribution group being sent TO. Not related to permissions for “send as” from the mailbox. By default, all users can send to distribution groups. For this case, it appears that it is restricted. Need to check parameters of Delivery Management for who can send to that distribution group.

Full access permissions doesn't give you any "send" rights, for that you will need to grant her Send As or Send on behalf of. Apart form the permissions, make sure she's actually trying to Send As the shared mailbox, the From address should be reflecting its address (and the "send using" value should match).

Hi @Safs-3080

Agree with michev. Send As Allows the delegate to send messages as if they came directly from the mailbox or group. There's no indication that the message was sent by the delegate.

You could refer to the official document to assign permission for userA

In Exchange online: Manage permissions for recipients in Exchange Online

 Add-MailboxPermission -Identity "sharedmailbox" -User userA -AccessRights FullAccess -InheritanceType All

In on-prem Exchange: Manage permissions for recipients

 Add-ADPermission -Identity "sharedmaibox" -User userA -ExtendedRights "Send As"
