Question

People get emails back saying my account may not exists or email may not have been delivered

Hey, I've been trying to apply for jobs and almost all of them call me saying they got that mailed to them after they tried to emailing me. Is there a fix for this or do I have to make a new account?

Hello

Did you receive the emails anyway, but they still receive this undelivery email, or you never received those emails?

If it is the first scenario,

Please complete these steps on a computer, not on a smartphone or tablet. Go to https://www.outlook.com and sign in.

Click the gear icon in the top right corner to open Settings.

Under Mail, review the following areas:

Rules

If any rules are listed, delete all of them.

Conditional formatting

If anything is set up there, delete it.

Forwarding and IMAP

If you see any entries or settings you did not create, remove them. Turn off POP and IMAP.

If it is the second scenario, go to https://account.live.com.

Under Your info > Sign-in preferences, review all aliases on the account. please tell me if your email address is still listed here?

Since you got the email sent to you, it is the first scenario I mentioned in my original post. Please exam/review those areas I listed out for you.

there's nothing under rules and conditional formatting just says " conditional formatting rules are not supportive for the selected account. "

Can you go to the undelivery bounce email, review the content in that email, does it specific say which email address doesn't exist?

For example, it typically says the following email address ******@xxxx.com cannot be delivered, or something along that line. I would like to know, is the referenced email address in that email actually yours?

In your outlook.com settings, did you review the Forwarding and IMAP secion?

You are welcome.

If you didn't add this forwarding, you might want to consider going through the following just to be safe, in case your account has been compromised.

Go to https://account.live.com.

Under Your info > Sign-in preferences, review all aliases on the account. If you see any alias you do not recognize, remove it.

Next, go to the Devices section of your Microsoft account and remove any devices you do not recognize.

====================

Please also do the following in Security section

Change your password

Enable two-step verification

====================

Go here https://account.microsoft.com/privacy/app-access Click on "Don't allow" for anything you don't recognize.

=======================

Then go to Security > Manage how I sign in and make sure all contact information belongs to you.

On that same page, scroll down to App passwords and remove any existing app passwords.

Also on the same page, click on Sign out everywhere. This is intended to disconnect any active sessions that may still be connected. Please note that this can take up to 24 hours to fully take effect.
