The SEPPmail365cloud PowerShell module has been built to simplify the integration Exchange Online (ExO) instances into the SEPPmail.cloud (SMC). The module requires you to connect to your ExO environment as administrator (or at least with Exchange administrative rights) via PowerShell Core and creates all necessary connectors and rules, based on the e-mail-routing type and region for you with a few commands.

 

The module itself can be found in the PowerShell Gallery at https://www.powershellgallery.com.  

The current version of the module as of May 2026 is 2.5.0.

 

In this manual we refer to a video of a Deep Dive Webinar on the PowerShell Module in January 2026, which you can find here:

We will repeatedly point out specific parts of the video for specific steps in the configuration. However, watching the video fully would give you a complete overview of the module and its usage.

 

Aspects to consider before changing your E-Mail routing:

• Routing Modes as explained in Configure Mail System
• the cloud region where your tenant was provisioned, see also your onboarding mail
