I'm looking for a way to find all users who don't have SEND AS SELF flag set in Exchange 2010. Without that flag users aren't able to send emails thru SMTP and it seems some users are missing this flag (especially users who used to be Domains Admins etc)
I guess this would have to be similar to query below although this should show users (well not quite as it hides the username) who have Send-as and I'm looking for users who don't.
[PS] C:\Windows\system32>Get-Mailbox | Get-ADPermission | where {($_.ExtendedRights -like "*Send-As*")}
Identity User Deny Inherited
