We have O365 which is just being used to authenticate to Office with ADFS and we have on Exchange 2010 on premises.
We would like Restrict external OWA and autodiscover for Office 365 as we have a scenario where users are downloading O365 on their personal computers outside the office and when they sign in with their O365 account and open Outlook they enter their password and all their work emails are on Outlook.
Is there a way where we can block autodiscover outside network and use all features inside the network? We would like webmail to be still accessible outside. We just need to block the Outlook option outside the network.
