Create a mail flow rule for Mesh in Microsoft 365

To allow email filtered by Mesh to be delivered safely without additional filtering from Microsoft, create a mail flow rule in Microsoft 365 for the IP ranges applicable to your region.

The following video guides you through the process:

Populate users through Azure Sync

To allow users to receive quarantine digests and create their own allow and block rules, populate them in the users table.

Azure Sync runs automatically every hour. For synchronized mailboxes that do not require an account in Mesh, select the mailbox and set it to Disable.

Import allow and block rules (optional)

Import a list of safe senders or domains by using the CSV template.

Update your MX records

Update your MX records with the values applicable to your service region.

MX records are region-specific, and no other records should be present.

If you use MTA-STS, update the MX entries there as well.

Create a connector in Microsoft 365

To prevent threats from bypassing Mesh filtering and to allow email from the service MTAs to reach your mail environment, create a connector for Mesh in Microsoft 365.
