Dear drosen9w,

do you get a certificate error and are you using IE?
I'd assume you do, and the problem being is that your browser fails to connect because you are connecting to another host than that in the certificate.
I.e. instead of connecting to http://www.server.com/exchange which the certificate refers to, you are connecting as you write above.
Try the following when you get the "Continue to this website" - note that the steps may differ depending upon you browser and version; this is for IE8:
1 When the Security Alert dialog is displayed, click Continue.
2 Click Certificate Error.
3 Click View Certificates.
4 Click Install Certificate to launch the Certificate Import Wizard.
5 Click Next twice, then click Finish.
6 When prompted, click OK.
7 In the Certificate dialog , click the Certificate Path tab.
8 Select the parent node that is displayed in Certification path.
9 Click View Certificate.
10 Click Install Certificate to launch the Certificate Import Wizard.
11 Click Next twice, then click Finish.
12 In the Import Wizard, click Next twice, then click Finish.
13 In the Security Warning dialog , click Yes and, when prompted, click OK.
14 Close and reopen the browser.
15 Try accessing you OWA.

Kind regards,

I have found the following to be occasionally true

If your OWA Server is on your internal network, or if it is on a domain, to which you are also connected from - you possibly don't need secure http (https://) - go with http://
