Hi,

I have been requested to configure a Pop up warning/message for emails sent outside our organization if there is an attachment. We are now running on M365 E3 with M365 E5 Security and I do not have that option there. From what I read, upgrading to M365 E5 would give us “oversharing pop ups” feature. 

Before I will go with upgrading all users to E5, I would like to confirm whether the above would be possible with E5 license?
