Most of my exchange clients have domain accounts and can register their exchange email accounts normally.
But If I register any exchange accounts, to a local user in a computer domain (that means a domain connected computer but uses a local account) I get a popup prompting a "connecting to autodiscover.collaborationhost.net".
When I provide the username and password my email are do fetched, but when I reopen outlook the popup shows again.
