OK great if we could give permission to a group then we could do it manually in SolidCP which isn't as good as doing it automatically but at least it would be better than having to add a user and then login to OWA or Outlook to do the sharing.

We don't use whmcs, just SolidCP on Exchange but I will look into that.

By the way: if it would be possible to add a group, then you could also use the default group, which is created with the organisation and which can't be changed/deleted. This group is updated automatically, when a user is added or deleted from the org.

Best regards
