A user with a claimed email domain tries to create a new workspace.

When you claim relevant domains for your Enterprise Grid organization:

"Any user with an email address matching a claimed domain who attempts to create a new workspace will be directed to join the Enterprise Grid organization, ensuring that all workspaces fall under centralized policies for security, compliance, and retention."

This process prevents rogue or unmanaged workspaces and ensures consistent governance.
