I'm running Exchange 2010 via SBS2011.  My Remote Web Workplace works fine remotely and internally.  However OWA does not.  I must add https:// in the beginning of the url in order for it to work.  If I don't, I get the 'Problem Loading Page' error.

Ideas?

Hi

You should be accessing owa by https://   only .

Have you installed a trusted certificate.

Thanks

Reading it now.  What's unusual is that internal to the LAN, whey you type www.domainname.com/owa it goes to the proper website, but external to the lan, it does not and requires you type https:// in front of it in order for it to work.

Seems that you are publishing OWA on TMG or another firewall.... make sure that http port 80 is forwarded to exchange server...

but again it is not a good idea to access it without https.

If the firewall is TMG, you need to create a deny rule to redirect http://mail.domain.com/ https://mail.domain.com/owa

It's a sonicwall TZ200.  Port 80 shows open via port checker.

Check the firewall, and if you enable http, make sure to confure http to https redirection as per the above link.

If you can access http from internal then it must be the sonicwall blocking http traffic from external or not forwarding it to exchange server ..

Had to create a NAT policy in Sonicwall that went from Public IP to Private open.  Opened Port 80 then could access OWA successfully.,
