When I run the command of "Add-ADPermission "Display Name" -User MyUser -ExtendedRights "Send As" where Display Name = my CEO's name, I receive the following error.
Active Directory operation failed on DC-SATXHQ-01.ual.com. This error is not retriable. Additional information: Access is denied.
Active directory response: 00000005: SecErr: DSID-031521D0, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0
+ CategoryInfo : WriteError: (0:Int32) [Add-ADPermission], ADOperationException
+ FullyQualifiedErrorId : 8E80C85F,Microsoft.Exchange.Management.RecipientTasks.AddADPermission
The command works fine with other user accounts...
When I inspect the user using Exchamge Management Console, I notice that "NT Authority/SELF" is not on the Send As permissions for my CEO's account, but on the other accounts the command worked on, NT AUTHORITY/SELF is.
I've done a few searches on how to restore this, but cannot find anything.
Any help would be much appreciated!
