Hi Rogboy1,
Thanks for taking the time to post about your issues in the Community. We're sorry to hear you're having some issues with this.
Before you can reset up the email on your Outlook client, you will need to complete some steps. Please log in to My Virgin Media here > Click on Account settings > Virgin Media Mail settings > scroll down to the App password section and click the Generate new App password button.
You should get a pop up message asking you to verify your email address and you'll need to use a 3rd party email address to continue. You'll be sent a one time passcode to enter on the next page to verify it's you. Once verified you'll then be given a new app password.
Wait 10 minutes and then use your Virgin Media email address and the newly generated app password to sign in on Outlook and this should allow access. This link will help with setting this up.
These changes have been put in place as Multi-factor authentication (MFA) is now required. Just as a side note, when logging in to My VM, you will need to use the third party email address and the original password you created for My VM as this is different to the app password.
Thanks,
