New PC - Microsoft Communication Services (Email Clients & Outlook)


I am having problems getting Outlook 2010 32-bit under Windows7 64 bit to connect to the Comcast hosted exchanger servers. The setting below work on an older pc with Office 2007 under Windows XP. My settings are as follows:

Microsoft Exchanger Server
Use Cached Exchange mode is checked


Encrypt data between Micosoft Outlook and Micorosft Exchange is checked

Use this URL to copnnec to my proxy server for Exchange:

Only connect to proxy servers that have this principal name in their certificate:

Exchange Proxy Settings 

On fast neworks, connecting using HTTPS first, then TCP/IP
and On slow networks are both checked

Using basic authentication

Microsoft security asks for my username and password,

then it times out and says that I cannot connect to the exchange server..

Again the mailbox does continue to work on the Office 2007 with XP but does not work with Office 2010 with Windows 7

Can you offer any suggestions on these settings?

Hello BOC_Tech,


Welcome to the forum.

The community would like to help but can you clarify a few items for us?

1. What is your domain name?

2. Do you get any error?

3. Are you using your personal copy of Outlook 2010?



Thank you
