To resolve the issue of adding an alias to your account, you need to ensure that the email address you are trying to use as an alias is not already associated with another Microsoft account. If you receive a message stating that the email has already been taken, it means that the email address is already in use by another account.
Here are some steps you can take:
- Use a Different Email: Try using a different email address that is not already associated with another Microsoft account.
- Create a New Alias: If you want to keep your current account and change your email, consider creating a new alias that is unique and not already in use.
- Check Existing Aliases: Make sure to check if you already have an alias that you can change to primary instead of trying to add a new one.
- Contact Support: If you continue to face issues, you may want to contact Microsoft support for further assistance.
Remember, when adding an alias, it is important to not use an email that is already linked to another Microsoft account to avoid conflicts.
