when l go to " all emails" the folder is not accessible.
The VM email service is not clever enough to have anything like an "All email" folder - you can only view or search your emails by checking each of the individual folders separately.
So when you say "All emails" folder that sounds as if you are using an email client or app, (possibly Outlook) to manage your email account. Using an email client or app is usually a much better way managing your emails than relying in VM's webmail service but even email apps can have their issues.
If you are using an email app or client it would be worth checking whether those missing emails are still present in your VM Webmail account on the VM website. For example in the Inbox or perhaps any other folders you have set up yourself.
Enter your VM email address into this link https://mail2.virginmedia.com/ and then enter the password when prompted. That will take you to your email account as displayed on VM's Webmail service.
If the emails are also missing on the VM website as well as your email app then clearly something has happened to delete the emails.There are a few things that might have caused that.
However, if the emails are present on the website it points to an issue with your email app/client, possibly just an issue with the way this "all emails" folder is handling and displaying your emails. Again, there are a few things that might have caused that.
Post back how things look on the VM webmail service and based on that answer some-one should be able to offer you the appropriate advice.
