Not enough information. For example, what version of Microsoft Exchange are
you trying to connect to? Reason I ask is that later version (Exchange
2010) will require encryption to successfully connect while an older version
(Exchange 2003) doesn't.

The other question I would ask is that is the Windows 7 Professional
workstation joined to the same AD domain that Exchange is installed into?
Are you logging onto the Windows 7 Professional workstation with your domain
userid/password or a local account?
