Managing personal Outlook.com account settings, security, and privacy
To replace a primary email on a Microsoft account, the supported path is:
- Go to Manage how you sign in to Microsoft at https://account.live.com/names/manage.
- Select Add email and add the new address.
- Complete verification for the new address.
- Select Make primary for the new alias.
- After the new alias is primary, remove the old one if needed.
If the account keeps looping during verification or shows a too many attempts message, complete the add-and-make-primary flow later and avoid repeated retries in the same session.
If the system still will not let the primary alias change after the new alias has been added and verified, use Microsoft support from the account help flow:
If the old primary address is a Microsoft domain alias such as @hotmail.com, @live.com, @outlook.com, or @msn.com, do not remove it unless certain. Removing that kind of alias is permanent and it cannot be associated with a Microsoft account again.
