Hi,
There is a prospect who has AD & Exchange on-premise 2003.
They would like to move to Exchange Online, but would like to maintain SSO.
Can it be done in the 2003 versions or do they need to upgrade first.
Also they have a group policy where users are not allowed to download pst.
If they are able to do SSO with ADFS, would they able to implement the same policy on Exchange online & IP based restrictions too.
