Hi @Mohamed Shehab,
Thanks for the question and using MS Q&A platform.
To enable the "Add" button and allow adding multiple MailFrom addresses, follow these steps:
- Certain systems need extra fields (such as domain verification or SMTP options) prior to activating the "Add" button.
- If your system requires verification of the first MailFrom address before adding more, check if there’s a pending verification step.
- If the button does not enable, reload the page or log in and out to remove possible UI bugs.
- If you're on an admin-managed system, make sure your account has the proper permissions to add MailFrom addresses.
- Make sure you are typing a valid email address (e.g., example@domain.com).
- Don't use additional spaces or special characters that don't belong.
Refer to below documentation for more information:
