Controlling settings, permissions, and membership within Teams and channels
Hello Hogstad,
My name is Adesoji and I'd be happy to help you out with your question.
Please note: This is a user-to-user community forum. I am just a user like you who helps others. I am not an employee of Microsoft.
The feature is currently unavailable to add users to a Teams channel from Microsoft Teams dynamically. However, users could dynamically be added to a Microsoft 365 group using specific attributes.
The dynamic Microsoft 365 group will provision a Teams channel. Please see https://learn.microsoft.com/microsoftteams/dynamic-memberships
I hope this helps.
Best Regards, Adesoji
