Mark,

This might mean that you are running this under a userid
that does not have enough permission. What userid do you
have the scheduler service running under?  Is it the same
userid that you successfully ran the GUI? If not, try changing
the scheduler service to run as a userid that has enough permission.
That way, when it launches Data Protection for Exchange, it will
be running under the context of that userid.

Thanks,

Del
