Exchange Server - Understanding "Send As" permissions

Asked By hume.spamfilte

I have got a test Exchange server set up in a VM, talking to an equally-test
AD instance.  My user object exists in AD, as EXAMPLE\hume, or
userprincipalname hume@example.com, and I have used exchange to create a
mailbox, primary email is "brandon.hume@example.com".

OWA works great; but if I join a local Windows 7 PC to the domain, use
Windows Live Mail, and send email I get the dreaded "Client does not have
permissions to send as this user" error.

I have turned on SMTP protocol logging, and I DO successfully authenticate.
I am connecting to the connector on port 587, TLS enabled and everything.
However, I cannot send any email as myself unless I explicitly grant SELF

I am mostly just trying to understand why this would be necessary.  My
reading seems to indicate that "Send As" should only be needed when you are
trying to send as a different user (spoofing a reasonable word?).  Is
that inaccurate?  Does any user need SELF/Send-As permission to send as
themselves?

How do you know this?


Does the account have elevated rights in the domain, e.g., Domain Admins
membership?  If so, create a new non-privileged account and see if you do not
have better success.


I would not call it spoofing since it is authorized.  Does the SELF account
have rights?  Honestly, I cannot remember if it needs to be there.
