SBS 2003 active sync errors 3005, 4004

SBS 2003 is running Exchange 2003.  About 40 users in AD, 15 of them use mobile devices with exchange email/calendar.
Problem started several weeks ago, Active sync errors 3005, 4004 for about 8 users who have mobile phones.  Many mobile users have no issues.  The ones that do, share many calendars(10+ calendars shared between some users), and those are the only users who are having active sync errors.
I ran Exchange connectivity test which shows that their 3rd party web site uses a wildcard at the domain registrar.  
About the time the error started, Google enterprise services were added to the domain which also added an entry in the DNS records at the registrar.

Any suggestions for isolating the problem?

Most of the 3005 errors can be ignored, but generally if there aren't problems.

You have the question in the SBS 2003 / Exchange 2003 zone yet you mention a 3rd party web-site using a Wildcard SSL certificate.  What is the relevance of the 3rd party web-site?

If you have Exchange 2003 on SBS 2003 then the SBS server will be where the mobiles get their data from so the SSL certificate installed there is the relevant one, not on a 3rd party website.

What is the FQDN of the SBS 2003 certificate?

Have a read through my guide and check your settings to make sure they are all as they should be too:
