I have a question i'm hoping someone can answer. It is exchange 2007, and outlook clients 2007, and 2010. We had to recently change the ssl port on our excange IIS to a different number than 443. We changed to 4400. Once this was done we made the forwarding changes in our router to point 4400 to the exchange server. Now we can connect to owa fine, and it works, but now sense the change our outlook clients that are on the domain get a error when trying to use out of office assistant. (Your automatic reply settings cannot be displayed because the server is currently unavailable. Try again later.) Out of office assistant works in owa. Now if I change the IIS port back to 443, and change the forwarding in the router. The outlook client out of office assistant works correctly. The probelm is I only have one public IP, and I now need the 443 traffic to go to another machine on our network a webserver, but I still need owa to work which is why I changed the port to 4400 on the mail server. I am just wondering is there anyway to get outlook client out of office assistant to work with that new port number. I would be thankfull for any help I may receive. Thanks agian.

You've posted in the wrong forum. This one is for Exchange 2013. I recommend that you post in the Exchange Previous Versions - Exchange Previous Versions - Setup, Deployment, Updates, and Migration forum. http://social.technet.microsoft.com/Forums/en-US/exchangesvrdeploylegacy/threads To answer your question, I wouldn't change the port, I would change the forwarding based on the OWA virtual directory. Send the Exchange virtual directories to Exchange. I'm not sure if you can do that with your web publishing device, but you can with a TMG or ISA server.
