2. Create mail connectors — route email from Office 365

Create two mail connectors. The first connector sends emails from Office 365 to Skyhigh Security Cloud for inspection, and the second accepts emails after they are scanned by Skyhigh Security Cloud.

Create a Security Group. To limit the impact of enabling Inline DLP, it's wise to set up a security group in Office 365 with a few email addresses that you can use to test. Once you're happy with the performance, you can then either add additional security groups, or use Inline DLP with all email addresses in your organization. See Manage mail-enabled security groups for instructions.

Make sure to set the following:

Type: Mail-enabled security group
Name: SkyhighSecurityCloudEmailDLP
Allow people outside of my organization to send email to this distribution group: OFF

2. Make sure to select Only when I have a transport rule set up that redirects messages to this connector when setting up the new connector.
