We have Office 365 and I am able to connect using OWA, and I can also log into Lync and SharePoint online successfully, but I cannot connect using Outlook 2010. I have run the install steps, setup the proxy settings exactly as colleagues have theirs set, but I am still prompted for a username and login once setup is done with Outlook. Am I missing a host file entry or something along those lines?
Someone else setup my colleagues and they are no longer in the office.
I have turned off the firewall temporarily with no luck there as well.
