Unfortunately, you cannot currently delete organizations in Domino. Additionally, once an organization is created you cannot rename it. There is an existing feature request ticket to add this to the platform and we hope to include this functionality in a future version of Domino
If I absolutely need an organization renamed, can an admin or Domino support do this for me?
Yes, if you absolutely need an organization renamed please write to us at email@example.com for assistance (for example, if it was created in error and has a name that conflicts with another user's desired username). The process requires a database update so we can only do this in cases where there is an urgent need, but in such cases we are happy to help.
