Is it possible to create a completely unique URL for a Workspace 365 environment?
This is possible for parties which host Workspace 365 themselves (server-wise). Contact your specific reseller to discuss if this is possible. If we (New Day at Work B.V. - Workspace 365) are hosting your Workspace, this is also possible.
Make sure you have a valid certificate (.pfx) for the URL you want to bind to the Workspace. Contact email@example.com for more information.
