Setting up multiple connections to the Microsoft Exchange server with Exchange Online and Microsoft EWS

You can define the connection to the Microsoft Exchange server and connect multiple different Exchange servers to the Groupware app.

To connect a Microsoft Exchange server, make sure that the SSL certificate is qualified and valid.

The following conditions apply for the impersonation user:

  • For Exchange Online in Microsoft 365: the user needs a mailbox (EWS and OAuth 2.0).

  • Microsoft Exchange server (on-premises): the user needs a mailbox (EWS and Basic) if they are to access public folders.

  • Enter the SMTP address as the user name to allow access to public folders.

For an additional Microsoft Exchange connection, you can select between Microsoft Exchange (on-premises) and Exchange Online. For Microsoft Exchange (on-premises), only Microsoft EWS is permitted. Exchange Online can use Microsoft EWS or Microsoft Graph.

If you want to delete a Microsoft Exchange configuration, make sure that the configuration is no longer used.

Let's assume you want to configure the connection settings for Exchange Online and use Microsoft EWS as an additional connection.

This is how it works

  1. Open the Configuration feature from the start page and navigate to E-mails in the Document management category.

  2. Select the entry Microsoft Exchange under E-mail management.

  3. Go to the Connection settings perspective.

  4. Select Enable Microsoft Exchange services.

  5. Enter all necessary parameters for the first connection.

  6. Click the plus sign to add the parameters as an additional connection.

  7. Enter the accepted domains for the Microsoft Exchange server. Separate the domains with a comma.

  8. Under Exchange API, select Microsoft EWS as the interface.

  9. Click Microsoft 365 under Exchange Web Services server, which causes the system to enter outlook.office365.com.

  10. Enter the Exchange Web Services port and the appropriate version under Exchange Web Services version. The default value is Autodetect.

  11. Set the authentication method for Exchange Web Services. For OAuth 2.0 (Microsoft 365), enter the Microsoft 365 directory ID, the Microsoft 365 application ID for d.ecs groupware, the Microsoft 365 API access key for Exchange Web Services, and the impersonation user for Exchange Web Services from Azure Active Directory. For Basic, enter the impersonation user and the password.
