Add Send-As & Receive-As Permissions to user at the database level in Microsoft Exchange

This is generally a very common requirement in case of updating the BlackBerry Service Account "BESAdmin" or also while implementing Backup Solutions which also demand for the Send-As and Receive-As rights.

Through Shell:
We can use the following command to assign the user the Send-As and Receive-As rights on all the databases.

Get-MailboxDatabase | Add-ADPermission -User "jack.sparrow" -AccessRights ExtendedRight -ExtendedRights Receive-As, Send-As, ms-Exch-Store-Admin

Through ADUC GUI:
The same activity can be performed from the ADUC.

1. Open ADUC
2. Enable "Advanced Features"

3. Locate the user and go to the "Security" tab

4. Now you can easily enable the required permissions.

Exchange Management Console:
The Send-As permissions can also be assigned from the EMC.
1. Go to Recipient Configuration

2. On The Right side of the pane you should be able to see the "Manage Send AS Permission" tab
