I cannot access OWA from outside my network
(extensive google search took me nowhere)

so...
OWA is accessible from local network
https://localhost/OWA

Firewall
Port forwarding 80 & 443 to exchange

what is also weird:
http://mail.mydomain.com/owa
Returns a 403, the 403 is located inside my network. (so it is kind of working!)
I have updated the 403 error & can see that it is definitely going through

https://http://mail.mydomain.com/owa
Page cannot be displayed

I am lost now, dont know what I can try

Thanks

You are getting the 403 error message when trying to use http because it is setup to force https.

What if you try going to https://mail.company.com/owa

What do you get then?

Have you setup the external OWA address within Exchange itself? Also double check your DNS records to ensure everything is pointing.

Then you'll want to make sure your web address is exact.

Since you are receiving the page cannot be displayed, check to verify all of your Exchange services and IIS services are running. You may also try an IISreset from the command line to restart the IIS services.

Can you check the Event Viewer on the Exchange server and post up any related errors?

Right..Out of all the posts I have read the last 2 days, I just figured out what it wasn't working.
I also understand that many things can go wrong, so thank you for your answers.

My solution:
I said that everything was working ok internally
I could also telnet my ip on port 443 OK

After moving away from looking the EMC & IIS, I turned out to my router.

The router management (allow management from the internet) was on & using https on port 443

I turned it off & freed port 443 for exchange & now everything working
