While working on Microsoft Device Driver domain, I found following most active and helpful forums,
1) OSR-Online: http://www.osronline.com
You can configure OSR-Online forum on email client and given client will be helpful for you.
2) Microsoft NNTP Server: msnews.microsoft.com
Following groups are available on Microsoft forum,
You can configure Microsoft NNTP server on email-client using above “OSR-Online Forum Configuration” process but you will use “msnews.microsoft.com” for Microsoft NNTP Server address. You will not need authentication cardinality to connect Microsoft NNTP Server.
NOTE: Some time few consultants will discourage you to use forums for help and will ask you to get consultancy from them. Please do not underestimate yourself and try google and other forums for help because “Everything possible but nothing is impossible”.
