outlook over http does not work since isp changed
Posted on 2011-10-30
We have an SBS2003 Standard Edition DC plus a Terminal Server running Windows 2003 64-bit Server.
We have staff located at several physical sites who use Outlook to connect to the Exchange Server in SBS via Outlook Anywhere (connec to Exchange over HTTP).
We also have users who use REmote Desktop Connection to connect to the Terminal Server.
Last week we changed ISPs. I had our domain host (who was our previous ISP) change the MX records to the new IP address.
Interanally connected systems run Outlook and can all send and receive email to both internal and external email addresses, so I figure the MX forwarding must be working.
As soon as I swapped over to the new ISP, RDC stopped connecting....not surprising. I had users change the server address from the domain name to the new IP address and that worked straight away. However, now four days later, I still can't connect via RDC with the domain name. I think this sounds like some sort of DNS issue, but I would have thought the IP/domain combination would have propegated by now.
I also discovered today that none of our off-site users can connect to Exchange with Outlook Anywhere. This is a big problem.
Any help would be great!
