With the Send Permissions granted to a mailbox/distribution list user, he/she can send messages on behalf of or as the Distribution List in which you configure these permissions.
You can configure the following Send Permissions in the Distribution List properties:
- Send On Behalf Of – Mailbox/Distribution List user is able to send messages on behalf of that Distribution List.
For example, you configure the Distribution List 'B' to grant the Send On Behalf Of permission to some mailbox/distribution list User 'A'. The User 'A' sends a message. In the 'From' field of the message will appear: User 'A' On Behalf Of Distribution List 'B'.
- Send As – Any Mailbox/Distribution List user is able to send email messages as the specific Distribution List. With the Send As permission, the recipients of a message cannot identify whether the message was sent by that Distribution List or another user that has been granted the Send As permission.
For example, you configure the Distribution List 'A' to grant the Send As permission to some mailbox/distribution list User 'B'. The User 'B' sends a message. The message will appear as if it was sent by the Distribution List 'A' (the 'From' field will indicate: 'Distribution List 'A' ).
One Mailbox/Distribution List user can be granted with one of these permissions only.
To configure the send permissions for the Distribution List, follow these steps:
- Go to Exchange > Distribution Lists.
- Select the Distribution List to configure the send permissions for.
- Move to the Permissions tab. The list of mailboxes and distribution lists granted the send permissions on this Distribution List opens.
- Click on the Add button.
- Select the respective send permission from the drop-down list opposite the name of a mailbox/distribution list you want to grant that permission to.
- Click Submit to save settings.
As a result, selected mailbox and/or distribution list users appear in the list of ones with granted Send Permissions for the Distribution List.
