For the relevant Azure AD target system, Edit a target system.
On the General tab, enable the Exchange Online Integration toggle.
Choose between Modern Authentication or Certificate Authentication (Recommended)

Enter username (above created account)
Enter password (above created account)
Certificate Authentication (Recommended)
Create an app registration in Azure with sufficient permissions (Requires at least Exchange Online permissions to create and update mailboxes.)
Assign certificate to app registration for authentication (in Azure)
Enter Organization (domain of tenant)

Ensure that the proxyAddresses mapping has been configured (see Configure initial mappings).
When Exchange Online is enabled, this mapping defines the SMTP addresses for target accounts.
