I started to set up mail under my own domain. I added some users and then ran in to problems so I deleted the entire organisation and started again.
The problem is when I try to create the same user now I can't as "they already exist". I therefore invite the user again:
When I do this nothing happens. No emails are sent etc.
If I try and login as the user and delete their account I can't because I get an error saying they are admins of the organisation I created and I should remove them first. I can't do this as they are pending users now and not admins:
Why is it not possible to delete this user or re-add them to the control panel?
