Re: telnet to smtp mail server Q
Lots of carriers block port 25 from dynamic addresses with whitelists to allow servers they know about through Maybe depends on where you are connecting from Can you telnet to other MX servers okay? That would give you an idea of whether its a carrier issue (although the McAfee and perhaps local firewall rules could equally block port 25 outbound from anything other than a known server Also could be the server is actually down - is there a 2nd priority server MX record?

Re: Exchange is history?: Moved two clients to GoogleApps this week.
There is a different cost model here, and some limitations but various upsides One big issue I see is if you have lots of shared mailboxes e.g. for client projects or other reasons then you have to pay for all of those as a license, as always it will be horses for courses What about Microsoft Live Cheers Duncan On 20/08/2010, at 9:59 AM, Stephan Barr wrote: Super easy.

Re: RPC/HTTP Revisited
One issue I had with installing a wild card certificate was in iiis expecting a client certificate for the rpc directory Somehow that changed during the certificate installation, I took this requirement off the rpc dir in iis and things came back to life. I found it using the rpc tools for server 2003, otherwise there were no error messages Then for some reason the setting would revert every few hours. Eventually rebooting evrything caused it to stick Good luck Cheers Duncan Sent from my iPhone please excuse the typos On 22/04/2010, at 2:58 AM, Michael B.

Have a different problem now. I am on the local network with a fully patched Windows XP virtual machine, and a fully patched installation of Outlook 2003. If I set up a standard user profile and configure it without rpc/http no problems, as soon as I add the exchange proxy settings for rpc Outlook just continually prompts for a password, and goes no further (I am not asking Outlook to remember my password here - I want to have it accept it when I put it in) Any tips on what I am doing wrong here would be greatly appreciated.

Re: Outlook using RDP over HTTP issue
Usually you have to have that cert installed in the Trusted Root Authorities, if his profile or machine changed or the cert changes you can get problems like this I tend to get people to check they can access webmail with no certificate errors in IE to verify the cert is okay Cheers Duncan On 20/01/2010, at 8:48 AM, Doug Rooney wrote: Stm.sonomatile.local is what the machine is called internally, webmail.sonomatilemakers.com is the external address, and yes we updated it end of Dec.
