OCS 2007 and PIC

I have been using LCS 2005 and PIC with AOL / MSN / Yahoo for about 2 years.  I just replaced our LCS 2005 Access Proxy with a OCS 2007 Edge server.   Everything is working perfect except for PIC with AOL / MSN / Yahoo.  I have 3 IM service providers configured and all our "allowed":  Yahoo! ... AOL ... MSN

The OCS event log keeps showing the following error too:

Federated partner federation.messenger.msn.com has sent a significant number of messages that have resulted in domain validation failures. There have been 7 such failures in the last 19 minutes.There have been 55 errors in total. This can happen when messages are sent to local users that don't exist, messages are sent from domains that the partner isn't allowed to send from, or when the partner sends messages destined to domains that this organization isn't responsible for.

Any ideas on where to even begin?  This new Edge server has a different public IP than my previous Access Proxy.  Does that matter?  It has the same certificate name on the external edge as the access proxy did.

Communicator shows AOL / MSN / Yahoo contacts as "Status Unknown"

Your configuration is more than likely correct.  It can take up to 30 days for Public to change your FQDN settings.  Typically the turn time is around a week from what I have seen.  The outside contacts will remain until your FQDN is fully recognized by the outside world.  Even though the certificate is the same name, your IP has changed and needs to replicate.  You can also contact Microsoft and have them update your PIC services for MSN, AOL to change theirs...etc
OK...I'll contact Microsoft Support in the meantime....
What was your change time frame?
I made the change early on 04/30.  Will be working with Microsoft Support today...maybe you are right about it taking a week...
