I created my original Microsoft account when I worked at Purdue University. Under my Purdue University overarching master account, there exists a (1) business account and a (2) personal account. The business account is named Purdue.edu. The personal account is also named Purdue.edu.

Within this Personal account, under the Purdue University overarching master account, I downloaded Microsoft Office 365 Family, which I added my wife’s laptop to as well.

I also have a Microsoft user account, not under the Purdue University overarching master account, which is named [PII removed]@outlook.com]. [PII removed]@outlook.com is also the name of my email account, created in Outlook, under my Personal account of the Purdue University overarching master account.

Now, I would like to disconnect my Purdue University Personal account from my Purdue University Business account. And, move my Purdue University Personal account into, or merge with, my [PII removed]@outlook.com personal account outside of my current Purdue University business/personal account. I will need to move my Microsoft Family 365 account to this [PII removed]@outlook.com Microsoft Personal account, and subsequently add my wife’s laptop back on this new Microsoft Family 365 account.

I do not want to lose my [PII removed]@outlook.com] email address already part of my Personal account connected to the Purdue University overarching master account.

When I simply try to rename the Personal account, under the Purdue University overarching master account, from Purdue.edu to [PII removed]@outlook.com], I get an error saying the [PII removed]@outlook.com] account already exist.

How do I do this?

    Hi, Mitchell Springer

    The Purdue work/school account and personal Microsoft account are separate identities that happen to use the same Purdue.edu address. They cannot be disconnected by merging the personal account into the existing Outlook.com account, and two personal Microsoft accounts cannot be combined.

    Here are some suggestions you can try:

    Sign in at https://account.live.com/names/Manage using the Purdue.edu address, then choose Personal account if prompted.

    Add a new Outlook.com alias and make it primary. Do not enter the existing Outlook.com address, because it already belongs to another Microsoft account, which explains the error.

    After confirming that the new alias works, remove the Purdue.edu alias from the personal account. This changes only the sign-in name, so the Microsoft 365 Family subscription, OneDrive data, and existing sharing with your wife remain with that personal account.

    Keep the existing Outlook.com account separate.

    If you specifically want the subscription owned by the existing Outlook.com account, it cannot be transferred. Turn off recurring billing, allow the current subscription to expire, then purchase a new Family subscription through the Outlook.com account and invite your wife again.

    Thank you for your patience in reading, I hope this information has been helpful to you.
