Setup
You can set up Email Security via:
With post-delivery deployment, Email Security scans emails after they reach users' inbox.
Post-delivery deployment includes Microsoft Graph API and BCC/Journaling.
With Microsoft Graph API, you authorize Email Security to scan domains via your email provider credentials. With BCC/Journaling, you send messages to Email Security via BCC or Journaling configurations within your email provider.
When you set up Microsoft Graph API, you get access to the following features:
- Auto-moves.
 - Directory synchronization.
 - Post-delivery response / Phish submission response.
 - Auto pull EMLs for reclassification whose disposition is "None".
 - Manually move messages to different inboxes.
 
If you set up Email Security via BCC/Journaling and you want to access the features listed above, you will need to associate an integration.
With pre-delivery deployment, Email Security scans emails before they reach users' inbox.
MX/Inline allows you to send messages to Email Security to scan before they reach your users' inbox. You may need to update your MX records.
With MX/Inline, you will not be able to auto-move emails.

- Directory synchronization.
 - Post-delivery response / Phish submission response.
 - Auto pull EMLs for reclassification for disposition "None".
 - Manually move messages.
