I have a user running Outlook 2010 and connected to Exchange 2010. I tried to create an e-mail profile for the user but Outlook failed to obtain the configuration. I have tested the Auto-discovery settings and all works fine.
Tried all sorts of settings and otherwise but no luck.
Eventually when a Outlook security box popped up asking for credentials it did not accept firstname.lastname@example.org but what it DID accept was domain\username which to me looked a bit odd.
It worked but what could be the reason behind that?
Any one can explain please?
