As you have read on the community forum, there have been issues for many email addresses in the past week or two, many of which need the attention of VM staff. The Forum Team (VM employees) will reach this thread as soon as possible as they work through the board in date order.
In the meantime, can you confirm you are a VM broadband customer, and that the email address you are having trouble with is linked to the billing account when you sign in at my virgin media? Don't post your email address or personal details, just facts. This will assist the community to diagnose the problem.
The Forum Team have been advising these first steps:
"Have you changed your password through your online Virgin media account? Also we would recommend doing an anti virus scan on all devices that you are trying to access the impacted email account from.
Please try the above first and if you still require further assistance please come back to us and we can assist you further"
Use this link https://mail2.virginmedia.com/ and reset your password by clicking onpasswordin 'Forgotten your email or password'. After things are fixed, you may also wish to check your auto forwarding and filter rules which may have been set up in your webmail.
Sorry to hear of the issues accessing your email account but thanks for taking the time to post on the forum and welcome to the community.
I'm going to send you a Private Message to get some more details from you to look into this further, can I also ask that you reset the password for the email address you're experiencing the issues with.
