403 Forbidden Fixed but Outlook App not working

[X-File]

Ok, follow on from the 403 Forbidden error which I.T. have now fixed:- the Private Message that I was continuing as its part of that fault, I was told to put it initially on here first !

Noticed this morning my phone asked me to sign into my account, I use outlook on it, (all other accounts ok) but as I do not know which of the 6 password changes I have done so far, So, I have reset my password.

Got back in to my webaccess without any issues, but phone still not letting me it.

Left it until the morning, but still not working, even after deleting the account off outlook app and putting it back in. Used these details:-

IMAP settings (recommended)
Host Name: imap.virginmedia.com
Username: your full Virgin Media email address
Password: your email password
Advanced settings
SSL Encryption: Enabled
Port: 993 (this may be automatically chosen by selecting SSL encryption)

SMTP settings
Host Name: smtp.virginmedia.com
Username: your full Virgin Media email address
Password: your email password
SSL Encryption: Enabled
Port: 465 (this might not be selected automating by enabling SSL, so please check)
Authentication: Password

Just get IMAP user name password not correct!

VM have recently changed the log in requirements for accessing VM Mail via third party apps.

If you change the password for the account in My Virgin Media > Account settings > Account details you will not be able to use the new password to access the account via an email client. Email client access now requires an app specific password which can be generated in the MyVM > Account Settings > Account details > Mailbox App password management

Great answer, now working!

Why don't just VM advertise that all users will need to do this for any 3rd party app that a user uses for email access.

Thank you

@X-File Good to read that this has worked for you.

To be fair to VM they do explain the need for an app password in their help pages: https://www.virginmedia.com/help/broadband/manage-email-account

Hi Graham,  I know this was a while ago, but you seem to understand the problem.  I am worried about generating the app specific password, as a fix to the error 403 problem (no access to webmail), because at the moment I can still access through my phone email client.  My understanding is that if I generate an app password I will then have to change that password also, and I don't want to lose my only link to my inbox.  Is there any other way to be able access the webmail?  Thanks
