Outlook 365 not sending using ntlworld address

[croftcroyne]

Hi. Any input would be gratefully received as this is doing my head in! I've read the various replies and comments on this helpful forum but to no avail. The error only happens with my ntlworld address, and is fine with outlook.com/gmail and virginmedia.com! I am running Windows 10, and Office 365

I have checked the email settings/password all correct. I have repaired then uninstalled Office 365 but exactly the same error message 'enter your user name and password for the following server...'

I have run the cmd suggestion with the following result (but am none the wiser, apart from the fact outlook doesnt send on the one address!)

C:\Users\steve>curl -v -url "smtps://smtp.virginmedia.com" --user *****.*********@ntlworld.com
Enter host password for user '*****.**********@ntlworld.com':

Any help would be fantastic! Many thanks.

Hi @croftcroyne, 

Welcome back to our community forums and sorry to hear you are having issues with outlook when using your ntlworld email.

Just to confirm, how long has this issue been ongoing? Are you able to access your account when login into your email via the virgin media webmail? If not, have you tried changing your password as seen here to see if the issue persists? https://www.virginmedia.com/help/billing-and-payments/login-problems.

Thanks,

[croftcroyne]

Thankyou Akua_A. On and off (more on than off) now since 30th September 2021. Yes I can access my email online via Virgin email, and not from my PC using the default mail app on Windows 10. 😞 Its easy enough to change to another email address in Outlook, but it has meant that my default email address is slowly changing! Any further thoughts? Many thanks , 

Best wishes,

Steve

Thanks for coming back to us @croftcroyne.

Have you tried to change your password since the issues started?

Hi Steven_L, Sorry for the delay, yes I have changed the password after the issue started.

Best wishes,

Steve

Thanks for keeping us posted on this Steve Just to confirm - does the same problem not happen when trying to send via the website/webmail directly?

With regards to the password reset, it's important that the password is reset to something new/never used before via your online account (virg.in/myVM), then you'll need to update the details in Outlook as well.

Thankyou Tom_F, The issue doesn't arise using webmail/website.

The password was new/unused and changed after the issue started (and not since)

Best wishes ,

Steve
