Question

Disable Mail going to Outlook without deleting account

E TO 20

I use an old Hotmail (Outlook) EM account for spam. Unfortunately, I'm getting almost 100 Spam EMs daily, which I delete every day. I would delete my Microsoft account, but I have a subscription to Microsoft Office 365 which is critical to me.

Is there a way to stop getting EMs sent to this mailbox while maintaining my Account so my subscription to Microsoft Office 365 will not be interrupted / compromised..

Thanks

Yes. You do not need to delete your Microsoft account or your Microsoft 365 subscription just because the old Hotmail address is receiving spam.

There are a few ways to handle this, and I would recommend changing/retiring the old email address while keeping the same Microsoft account.

Best option: Add a new email alias, then remove the old Hotmail address

Microsoft treats email addresses attached to your Microsoft account as aliases. Your aliases share the same account, subscriptions, OneDrive storage, settings, and password.

Heelo

What you can do is to give your account a different alias, then delete the current hotmail email address. This way it is still the same Microsoft account, nothing under that account changes.

Sign into your personal account via this link: https://account.live.com

Go to Your Info > Sign in preference, Add an alias.

You have two options here:

Create new: this will allow you to use the native domain outlook.com to create a new alias.

Add existing: this will allow you to add a 3rd party email address, such as yahoo, gmail, as long as they are not already associated with another Microsoft account.

Once added, make this new alias your primary alias, then you can delete the other email as alias, and that email is free from this Microsoft account instantly. If people email the old alias/email address, it will not come through anymore.
