Why do I receive an error message when I try to create a group?
A red box stating "Group name is already in use." will appear when attempting to create a group that already exists within your organization in OnBoard.
Even as an Administrator, you will not have access to see every single group that has been created, unless the person who created that group has granted access to you. Most likely, another Admin in your organization has already created the group you're trying to create, and you just need to be granted access to it.
