The error message you are encountering when trying to add "Edit" rights to your group indicates that the security group contains an invalid share role set, specifically the role of "Collaborator." This typically means that the permissions or roles assigned to the group do not align with the requirements for sharing or editing in the context of Microsoft Copilot.
To resolve this issue, you may need to check the following:
- Review Group Roles: Ensure that the roles assigned to the security group are appropriate for the actions you are trying to perform. The role of "Collaborator" may not be valid for the sharing settings you are attempting to apply.
- Adjust Permissions: If necessary, adjust the permissions of the group to ensure they meet the requirements for editing and sharing. You may need to consult your organization's policies on group roles and permissions.
- Contact Support: If the issue persists, consider reaching out to your IT support or Microsoft support for further assistance, as they may have more specific insights into the configuration of your environment.
Make sure to provide them with the exact error message and any relevant details about the group settings you are trying to modify.
