Hi
I have some existing Exchange online users and would now like to deploy ADFS for SSO.
As I understand it when I federate the domain all existing users will sign-on with SSO.
I've two questions:
1) What impact will this have on the existing users? Will it affect their current passwords
2) Is there an easy way to confirm the deployment before federating the domain? I'd like to avoid any outage to the users.
Cheers
