then a service can easily read the Exchange database; anyone with server
access can read mail across all mailboxes. In fact, Microsoft supports
this
type of setup with impersonation, e.g. a global user that can query any
mailbox it has permissions to within Exchange. This is how some EWS
integrated applications work. It wouldn't be that far fetched for the NSA
to incorporate the same type of query to monitor the mailboxes -- even
subscribing to change notifications so it only queries and collects when
a
new mail item has arrived. Additionally, Office 365 can simply create a
journal rule and have all inbound / outbound mail journal to a location
that makes it easier for snoops to look through the messages, e.g. an
external SMTP endpoint, all without the end customers' knowledge.

If anyone has any questions on Exchange they, too, can contact me off
list.

Just my 2-cents.

Any what's to say that email addresses at Office 365 aren't just mailing
lists where you get a copy and so does $FEDAGENCY.  That's how my kids'
email addresses work at home :-)

You spy on your kids? I thought not being able to put a lock on my door was
bad...
