Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Dear Gary,
Good day! Thanks for posting in Microsoft Community. We are happy to help you.
For your query, I am afraid the external users won’t receive notifications when the task is assigned to them. I apologize that this caused inconvenience to you. Based on the situation, I would like to suggest you vote for the suggestion in Microsoft Feedback Portal where other members voted for a similar idea. It’s the platform for us to hear your voice and improve our products.
As a workaround, you may use Power Automate flow to send notifications to external users. Here is a thread where members discussed sending emails to external users. If you have more concerns about building flow, since we have a specific channel Microsoft Power Automate Community coping with such building flow questions, I would like to suggest you post a new thread there for expert help.
Appreciate your understanding and patience.
Sincerely,
George | Microsoft Community Moderator
