Godaddy Certs don't Support .local anymore - what can I do to fix the certificate errors that pop up in outlook?

I have a few client networks that were setup with the domain .local including exchange on those networks.  In the past I was able to get a cert with servername.domain.local and everyone could connect with outlook inside and outside of the network with no issues.

Now Godaddy is not supporting any local domains.  When one of the certs expired I just put in for mail.domain.com and autodiscover.domain.com.  OWA works with no issues and mail flow was not affected.  The issue now is that when anyone connects outlook to exchange a pop giving a certificate error for servername.domain.local

I don't want to rebuild the ad on these servers so they are all domain.com instead of domain.local - what are the work arrounds?  If I build a cert server on the network and create an exchange cert for servername.domain.local will outlook still give the warnings since it was a self created cert?

Any help would be greatly appreciated

Thanks

By default with a .local domain most likely your client access server, web services, and OAB directories are the .local.  You would simply update these to the external DNS name so they match your certificate.  

 You would create an internal DNS zone that matches your external.  Then on exchange you would update those services to reflect the change.

 You can check out this little informative article that has some powershell commands to change the services and what you need to restart in IIS to get them to work with a .local domain.
