Question : MS Exch2k7 - MAPI RTF Default setting?

I'm trying to find out where to setting a system wide setting in Exchange 2007.  It is the MAPI RTF setting that can be set on mail contacts.  Mail contacts can be set to always send as RTF, never, or use system default.

How can I view/set this system-wide default.

Background info on this is at the following Q if you wish to read why I'm asking this:

hi,

EMC > Org config > hub transport
Remote domains (unless changed from default, you may only have "Default *" affecting all remote domains)
Open the required remote domain entry
Click the message format tab
You have exhcnage rich text format options here

If there is a prolem with a single remote domain, you may just want to create a new remote domain and make the required changes only to affect that domain.
