When adding an additional e-mail address in Microsoft Account, the error message is displayed:
This email belongs to an organization, so you could lose access if you leave. Please enter a different email address.
The e-mail address in question has been removed from all organizations, and when trying to sign in with it, Microsoft Online responds "This username may be incorrect. Make sure you typed it correctly. Otherwise, contact your admin."
How do I make this e-mail available again as alias?

I get this error message too. The "organization" is my own domain name registered through godaddy. I pay for the home subscription myself directly through MS. What can I do to change the email address as I don't want it associated with my (very ancient) hotmail account?

Hi, thanks for reaching out.
Before anything, can you confirm if that email was ever used as a work or school account under Microsoft Entra ID?
The message means the email is still linked to an organization’s tenant. Even if the account looks deleted, it may take up to 30 days before Microsoft fully releases it.
You’ll need to contact the organization’s IT admin to remove it completely from Entra ID. After that, try adding it again as an alias from your Microsoft Account settings at account.microsoft.com under Your Info, then Sign-in preferences.
