Configure Exchange Online
For more information, see Exchange Online.
For the relevant Azure AD target system, Edit a target system.
On the General tab, enable the Exchange Online Integration toggle.
Enter a Username.
Enter a Password.
Enable the Use Modern Authentication toggle to use Modern authentication instead of Basic authentication. This must also be configured in Azure AD.
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.

Do not attempt to map the mail attribute when Exchange Online is enabled.
Exchange Online is now enabled, and mailboxes will be created when Account entitlements are granted for this Azure AD target system.
