Unified From Address Handling Across Email Authentication Modes
Mail Server Configuration now supports Microsoft 365 Email authentication for portal email. Portal Administrators can configure a single email domain using Azure app credentials instead of a service account.

Go to Mail Server Configuration
Set Authentication Mode to Microsoft 365 Email
Enter Email Domain, OAuth Client ID, Secret Key, Client Secret Expiry Date, and Tenant ID
Select Save
The Email Domain Credentials list always shows a single row, populated with saved values or left blank for a new configuration
Only one sending domain is supported, so + Add Domain and row deletion are not available
All fields are required, and the Email Address domain must match the Email Domain
Configuration changes are saved as a single transaction
SMTP settings remain hidden when Microsoft 365 Email is selected
Recipient limits and batching behavior are unchanged
NOTE: Validation prevents saving if required fields are missing or the email address domain does not match the configured domain.
NOTE: Domain mismatches generate an authentication failure at send time. If Microsoft 365 is unavailable, the email is marked as a delivery failure and follows the existing retry process.
Portal users cannot view or modify these settings, and all portal emails continue to use the configured system sender address.
