I set up a WHS at my office today, and it works great. I was able to use the web access without any problems. But the minute I came home and tried to access, I got the following message. "The server at ******.homeserver.com is taking too long to respond." So I went into my router and forwarded ports 443 and 4125, same problem. Any help is appreciated.
You also need to forward port 80 to your server. Also, if your work is a corporate environment, they might have those ports blocked so no one can access them from the outside.
