INFO: Pre-Provisioning for MailMarshal Cloud (Integrated Mode)

 

This article applies to:

  • Trustwave MailMarshal Cloud (M365 Integrated Mode)

Question:

  • What setup should a customer perform in the M365 environment to facilitate provisioning of the MailMarshal Cloud tenancy?

Information:

This article highlights information required and a configuration item you must complete in your M365 environment before your MailMarshal Cloud account can be fully provisioned. For full details of the product features and web interfaces, see the SEG Cloud Customer Guide and the Web Console Help.

Tenant administrator credential

To complete setup on the first login to MailMarshal Cloud, you will be required to provide a Global Administrator credential for the M365 tenancy.

Tenant organization hydration

MailMarshal Cloud automatically configures required settings for mailflow. To ensure that automated configuration of settings proceeds smoothly, the tenant M365 organization must be "hydrated". 

  • "Hydration" refers to the creation of individual tenant copies of some M365 settings that are not often customized.
  • To complete hydration, run Windows PowerShell and execute the following commands. Use a Global Administrator credential.

$cred=Get-Credential tenant_admin@tenant.onmicrosoft.com 
$EOSession = New-PSSession ‑ConfigurationName Microsoft.Exchange ‑ConnectionUri https://ps.outlook.com/PowerShell/ ‑Credential $Cred ‑Authentication Basic ‑AllowRedirection

Import-PSSession $EOSession -AllowClobber
Enable-OrganizationCustomization

Other integrations

If you have previously configured another service that uses connector routings to integrate with M365, you must de-provision the other service before completing setup in MailMarshal Cloud. 
  • Follow the de-provisioning instructions for the other service.
