"This email is part of a reserved domain"

Hello,

Thank you for coming to the forum. My name is Fuad, If you do not mind me coming in and explaining what happened, I will still give you the steps to contact support, but they will not be able to assist you.

First, I am very sorry about the situation you are currently facing.

From reading your post, you added a new alias, and then removed the old one mistakenly during this process, and now it is not letting you access the old alias any more?

Alias, is for creating a new way to sign in and not to rename your email or unlink it. If you remove the previous primary email after making another primary (even in error), you will not be able to create it or access it again, especially if the previous primary ends with @hotmail.com, @live.com, @outlook.com, or @msn.com. If removed, you have mistakenly deleted that account forever. Microsoft do not recycle email address, so once removed, it is permanently blocked from being used again.

When you try to sign back into the account, it will say it does not exist (because it has been removed). If you try to create it again, it will say already used because Microsoft has locked that address, and no one including you can ever open an email with that address again.

You can read all the above from this Microsoft documentation (under remove alias): https://support.microsoft.com/help/459b1989-356d-40fa-a689-8f285b13f1f2 .

I am sorry that email address is gone for good.

There is no resolution, you will need to contact all the services linked to the email address and ask to change your email on file.

Hi Omar, My name is Umar, and I'd be happy to help you out with your question.

Please note: This is a user-to-user community forum. We are users just like you who help others. We are not employees of Microsoft.

If you are trying to restore your old email account and you are receiving the message "This email is part of a reserved domain. Please enter a different email address," it is possible that the email address you are trying to use is not available for use. This could be because the email address is reserved by the email service provider or because it is already in use by another account. To restore your old email account, you can try the following steps:

1. Check for Account Recovery Options: Explore any account recovery options provided by the platform. This might involve additional verification steps to prove your identity. Look for options like account recovery forms, two-factor authentication, or other identity verification methods.
2. Provide proof of ownership: If you can provide proof of ownership for the old email address, such as previous emails, account information, or any other relevant details, it may help in the recovery process. Gather any information or documentation that can verify your ownership of the old email address and provide it to the customer support team.
3. Be patient and persistent: Recovering an old email address can sometimes take time and require persistence.

I hope this information is helpful. Please let me know if you have any other questions.
