Hello.
I've implemented an AD FS server and DyrSinc on my corporate network. I don't have a AD FS proxy.
We also are running an old SBS 2003 server with Exchange 2003, so Autodiscover is not available.
RPC over HTTP is working fine as i already migrated one mailbox with success to the cloud.
If i go to portal.microsoft.com and i type my e-mail migrated account with our domain, automatically i get logged on, so SSO on-premises is working fine. Also, with the Desktop Setup, the SSO worked perfectly.
When i try to configure Oulook 2007, i have no success. I use my domain account and also the @company.onmicrosoft.com. Outlook tries to do Autodiscover but as we don't have that feature, we have no success.
I've tried to manually put our Exchange Online server and it connects with my domain account. But it asks for the credentials and i can't log in. I'm using the corporate credentials.
Since i am on a domain joined computer inside my network and SSO works fine for portal.microsoft.com, why i can't log in on Outlook 2007? Do i really need a proxy, even if i connect inside my network?
Thank you.
