Quick reference:
Settings -> Integrations -> Exchange settings
Introduction
In Workspace 365, it is possible to configure your Exchange Hybrid setup when having oAuth2 as Single Sign-On method configured. Therefore we use integration credentials.
Configuration
Step 1. Enable Exchange
As an admin, go to:
Workspace admin settings.
Go to Integrations.
Select Exchange settings.
Check the checkbox Enable Exchange.
As Exchange server type, choose Office 365.
Check the checkbox Use integration credentials for Exchange connectivity.
Normally Exchange On-premise uses integration credentials for authentication. However, if Modern Authentication is enabled in Microsoft Entra ID (previously called Azure AD)/Exchange Online, you can leave the integration credentials unchecked and authenticate using oAuth2 (click here for more information). When unchecked, the user's UPN should be equal to the primary smtp address.
Step 2. Integration credentials
Now the users' integration credentials must be configured. This is done at user level and must therefore be done manually for each user:
Go to Settings.
Select Integration credentials.
Click New to configure a new set of integration credentials.
Enter the username and password, and remember to check the checkmark for Exchange connectivity
