A collaborative workspace app in Microsoft 365 designed to help teams co-create, stay organized, and work together in real time across apps and devices.
Rob,
The Loop app currently requires each Loop user in an AAD tenant to have an Exchange license assigned to them. If not, users will experience failures in the Loop app, be unable to create new Loop workspaces, will not receive notifications or signals when users collaborate and update, and other experiences may also fail.
You can resolve your issue by assigning an Exchange Online license to all users in your tenant who need access to Loop.
Let us know if you have any questions.
Thanks,
Derek
