Telecommuting from my home office, I have been unable to connect to the Exchange server of my organization. I have followed my orgs instructions carefully. This is what I did: Connected to cisco VPN successfully Setup, selected: "Manually configure server settings or additional server types"; next, selected, "Microsoft Exchange or compatible service" Next, Added the Exchange server designated by my organization and my organization/Exchange User Name Unchecked "Use Cached Exchange Mode" entered my work/Exchange username/password Selected "Check Name"-- But a "Windows Security" / "Mail Application" with a notation of the computers "Domain"box pops up with fields for a Username and Password. I tried entering my Win 7 username for my user account--Then I get a pop up stating "Outlook cannotlog on. Verify you are connected to the network and are using proper server and mailbox name. The connectionto M.Exchanges is unavailable.Outlook must be online or connected to complete this action." Also tried entering my Exchange user name and password. Nothing works. Can anyone help?

If you are using a machine that is not a member of the domain, then you need to enter the username and password for the office account in the format of domain\username and then the password, unless things are setup differently. The computer's domain comes up because the machine is not a member of the domain, and it tries that by default. Simon. Simon Butler, Exchange MVP Blog | Exchange Resources
