I have Exchange 2010 running on a single 2008R2 server.
I am using Citrix Secure Gateway which is using SSL Port 443.
When I access the Citrix Secure Gateway from a remote location I am forwarded from SSL port 443 to the internal Citrix Secure Gateway server.
That all works perfectly well.
Now I have installed Exchange 2010 and my end user wants to access Outlook remotely from PCs, Macs, Blackberries and IPhones.
Therefore SSL is required, but I am already utilising SSL port 443 for Citrix, so I have to use a different SSL port, I chose 448.
I have a UCC/SAN SSL certificate from GoDaddy with the following URLs
I have created a DNS 'A' record directing autodiscover.externaldomai
nname.com to the external facing IP Address of the company.
OWA seems to works perfectly well using https://autodiscover.externaldomainname.com:448/owa
Office 2011 for Mac Outlook seems to work perfectly well.
Blackberries seem to work again using OWA URL.
Problems with IPhones which I'm still investigating.
Internal Outlook works but puts up an irritating warning after each invocation:
The certificate it is being presented with is the self cert certificate I use for Citrix Secure Gateway:
So I'm assuming Outlook is heading off looking for autodiscover.externaldomai
nname.com and coming back in on SSL port 443 and being forwarded to the Citrix Secure Gateway server.
Also Outlook Out-of-Office fails with the following error:
I believe this is caused by the same SSL port issue as above.
One point to note is that my internal domain name is different from my external domain name and unfortunately the internal domain name is used externally by a completely separate 3rd party.
My questions are:
Can I configure Exchange so that it uses port 448 for SSL rather that port 443 for all services or is there any other method I can employ?
Can I force the Exchange server to look for autodiscover.externaldomai
nname.com through internal DNS resolution rather than heading off externally to resolve it which is how it appears to work?
I'm sure once I have answers to these questions others will surface....
