Dynamics 365 Hybrid Exchange Online Configuration

Introduction

The Microsoft Dynamics CRM E-mail Router has been deprecated, and the Office 365 authentication type and Regional Discovery endpoints are approaching their EOL (Deprecation of Office 365 Authentication Type and Regional Discovery Service Deprecated). This has resulted in a need to move to Server-Side Sync before March 1, 2021. But before we dive into a Dynamics 365 Hybrid Exchange Online scenario, let us recap the current state of affairs.

Understanding Dynamics 365 Hybrid Exchange: How to Migrate E-mail Router Settings

For simple scenarios, migrating settings from the e-mail router to server-side sync is straightforward.

Supported and Unsupported Configurations

For Dynamics 365 on-prem deployments, review the following article:

For Dynamics 365 online, review the following article:

Supported e-mail service configurations for server-side synchronization – Power Platform | Microsoft Docs 

With that out of the way, I recently came across a scenario similar to the one shown below: 

There are two separate Office 365 tenants:

  1. Contoso.com 
  2. AdventureWorks.com 

Dynamics 365 instance was under the Contoso.com tenant; however, the Exchange Online was under the AdventureWorks.com tenant.

The current setup was using a Forward Box mailbox setup. The e-mails were forwarded from [email protected] – created as a queue in Dynamics 365 – to a forward mailbox, contoso.com, and the e-mail router would then bring the e-mail to Dynamics 365.

However, as we know, we had to migrate to server-side sync with the e-mail router, which had been deprecated, and the regional discovery service was looming shut down.

This case required creating a Hybrid Exchange Online profile.
