I have been unable to log into my email on any computer for weeks I can access on phone but not log in on any computer. I have important emails saved which I need to work with from a computer. Each time I login it says wrong password then I try resetting & it says unknown username.
When you say 'any computer', is that by using a web browser to access the webmail version of your emails?
The unknown username message is a bit of a worry as it would indicate that the email address in question is not linked to your Virgin Media broadband account (assuming that you are a current VM broadband customer). In such a case the email address is regarded as being orphaned and as such is prone to being deleted at any time. Often when this happens, the access to it via webmail goes first and access via a client application last for a bit longer, which would explain why it still works on your phone.
A member of the forum team should come to this thread shortly (I'll escalate it to them if not) and offer to contact you directly to see what can be done.
Ah then in that case, I'm sorry to say that almost certainly the email address, mailbox and all the email within it has been marked for deletion and, indeed the process is already underway. This all should be done after 90 days of you leaving but from time to time the process isn't down in a timely fashion and the mailboxes can linger on for far longer, but eventually the clean-up process catches up with them and they are deleted.
All I can suggest is that you quickly set up an alternative email address with another provider (gmail, outlook etc.) and while you still have access to your VM account on your phone, you quickly forward any messages you want to keep to the new address and start letting all of your contacts know.
