Exchange 2010 multi tennant Autodiscover Issue

I am using the IIS redirect option as my DNS server does not support SRV

http:// social.technet.microsoft.com/wiki/contents/articles/6818.exchange-2010-multi-tenant-autodiscover-service.aspx?wa=wsignin1.0

All is setup correctly and everything states successful when testing Autodiscover yet I am still prompted when opening Outlook RPC over HTTPS with "The name on the security certificate is invalid or does not match the name of the site"

Results of Test E-mail AutoConfiguration test (use AutoDiscover)

Autodiscover to http:// & https:// domain1- failed (0x800C8203)

Autodiscover URL redirection to https:// domain2 (host domain)

Autodiscover to https:// domain2/Autodiscover/autodiscover.xml - Succeeded (0x00000000)

Does anyone have this working without this prompt?
