Tip: If this is your first time setting up a customer in Mesh (or even if it’s not), it is worthwhile familiarizing yourself with this checklist ⟶ Before You Start Checklist

Step 1: Click edit on the customer account on the Customers page

After you’ve completed the setup form, click on the edit icon to the right of the customer’s name to open the customer modal.

Step 2: Click authorize

Select "O365 Authorize" to permit Mesh to connect to your Microsoft 365 tenant. This will take you to the Microsoft 365 login page.

Once logged in, you need to accept the permissions. This will take you back to your Mesh MSP portal where you need to click accept again.

Step 3: Click Sync to populate mailboxes

Clicking on the Azure Sync will populate all mailboxes in Mesh.

Step 4: Create a mail flow for rule for Mesh in Microsoft 365

This step only applies if the policy for this customer utilizes the Mesh quarantine.

To ensure Mesh quarantine digests and any emails released from the Mesh quarantine are delivered without additional filtering by Microsoft, you need to create a mail flow rule in Microsoft 365 for our IP ranges.

This video walks you through the process step by step:

• Ensure that the IP ranges applicable to your region are used. You can find this here

• View our step by step guide on creating a mail flow rule.

• Visit Microsoft’s documentation on this here

If you are moving from another Secure Email Gateway, you will likely have an existing connector in place to reject emails that aren't sent from a specific IP range.

You will need to update this to include Mesh’s IP ranges so that Mesh quarantine digests and emails released from Mesh quarantine are delivered.

You’re all set. Your email is now being scanned by Mesh 365.
