You are correct Michael, however, on a staff of 60 we only have 4 members who are accessing the mail server using BIS. Since I have been monitoring the W3SVC logs, the ips appear to be static.
I'm going to test with one of the staff that has their personal RIM connecting to get the email. If I see good information generated in the logs, then I'll add the other ips as well.

What do you hope to secure that isnt wide-open via OWA or anything else that can utilize OWA connectivity, etc? You're gonna have a lot of IPs to block. A LOT. -- ME2 On Mon, Mar 16, 2009 at 3:28 PM, Thomas Gonzalez <tgonza...@girlscouts-swtx.org> wrote: > *****Bump***** > > > > From: Thomas Gonzalez > Sent: Monday, March 16, 2009 11:50 AM > To: MS-Exchange Admin Issues > Subject: question on Delivery Restrictions > > > > Our environment is as follows: Windows 2003 sp1 with Exchange 2003 > 6.5.7638.1 with Ninja as our line of defense. > > > > So I am trying to prevent our RIM BIS users from connecting up to our server > via OWA, which I see is the source to allow them to retrieve their email.
