Connect Dynamics 365 (online) to Exchange Online

Connect Dynamics 365 (online) to Exchange Server (on-premises)

But we faced an issue where we got multiple generic errors and had no clue what seemed wrong. We raised a support request and made sure we followed all the prerequisites and it did the work for us.

Starting with the Prerequisites

  1. Microsoft Exchange Server.
  • You need to have a supported Exchange version i.e. Exchange Server 2010 Service Pack 3, Exchange Server 2013 Service Pack 1, or Exchange Server 2016.
  1. Basic authentication.
  • Basic authentication must be enabled in Exchange Server along with any other authentication type your Exchange server is using.
  1. ApplicationImpersonation role.
  • You need to create and configure a service account with the ApplicationImpersonationrole in Microsoft Exchange.
  1. Secured connection.
  • The connection between Dynamics 365 (online) and Exchange must be encrypted via TLS/SSL (HTTPS).
  1. Exchange Web Services (EWS).
  • Connections to EWS must be allowed through the firewall.
  1. Dynamics CRM User.
  • You have to create an account in Dynamics CRM, with the same user details that you used to create the service account in Exchange on premise. Make sure the email id at both places is the same.

While configuring the above steps, you need to make sure your exchange has the necessary permissions. Below is what helped us.

  • You will see a pop up of all the properties of the users mailbox, click on the email address tab on the left.

We used SMTP which is the default radio button, so we don’t change it.

  • Enter in the alias email address.
  • Click on OK to go back to main screen.
  • Click  on the save button to save your changes.

  1. Now login to Dynamics 365

Note: Under Credentials the same user should be used who has the impersonation role. Click on Test connection and check the result.
