New SSL certificate needed for SBS2011 with 5 email domains

Hello Experts - we have an SBS2011 server with a self-signed certificate which has been working fine until we created autodiscover DNS records to fix calendars for Outlook Anywhere staff.

We have a single static public IP address

Out set up is like this:

the cn of the existing cert is remote.company.com.au

Outlook Anywhere proxy server :  remote.company.com.au

This server also collects mail for 5 other domains.

The autodiscover DNS address for each of these domains looks like:


Autodiscover.company.com.au
Autodiscover.company2.com.au
Autodiscover.company3.com.au
Autodiscover.company4.com.au
Autodiscover.company5.com.au
Autodiscover.company5.com.au

We have one static IP address

Outlook now produces this error about 30 seconds after opening (see attached)



I checked ClientAccessServer and WebServicesVirtualDirectory settings in Exchange and they look fine

I think we need a new certificate but don't know enough about them

Someone has suggested a UN / SAN certificate such as from:

Any help appreciated

thanks

You can create a CSR in Exchange with all the domain names required and submit the file to the CA, they will provide you with required certificate.

You can go to godaddy.com and check it.

On SBS 2011, you need to create the certificate request through Exchange, but enable it through SBS. If you do it any other way then you get problems.

You will need to include remote.example.com and Autodiscover.example.com.
Watch the SSL wizard as it will try to set example.com as the common name - you need to change it to remote.example.com.
