Sophos XGS Delete a group imported from the AD

Hi admin_idl ,

Thank you for reaching out to the community, User Group not visible on UI ?
Check user-based (match user) is not currently turned on for that rule. 

It is about a group from the Active Directory which is to be deleted and this message appears when deleting it

Seems like the user is already in some kind of configuration.

Every user gets a group as primary group in XG. So check the group name of the user and check, whether you use this group already in the modules (like WAF, SSL VPN etc.)
