Frequently Asked questions
Can Proofpoint Essentials direct emails to both Exchange and Office 365?
Proofpoint Essentials can only send to one destination. It is best to send it to Exchange and have emails redirected from there.
Which import users option should I use, Active Directory or Azure?
This will depend on which one has the full users list for your company.
I am getting an NDR for relay access denied on a user already migrated to Office 365. How do I prevent that?
A connector will need to be set up in Exchange so emails redirected to the migrated mail box go directly to Office 365 and not be sent back through Proofpoint Essentials.
