Dear RVCom,
I'm available right now.
I am an exchange Specialist and already install, configure and support SBS version.
SBS is a custom Packaging of Infrastructure components. For this reason ,you should not manage user accounts with traditionnal tools.
Actually, temporary profile is, in many case, a permission issue.
Let me connect to your infrastructure with a remote tool (like Teamviewer). that i can fix your issue.
Best regards,
Michael.
