ewalk1952​ "is this Virgins' way of removing long term customers "
What Virgin Media certainly have been doing for quite a while is to close down Virginmedia, Virgin.net, Ntlworld and Blueyonder email accounts that are no longer linked to a live VM paid for service such as broadband.
See this for their explanation of that:

Unfortunately, in some cases long term customers may have had a new VM broadband account set up at some point and their existing VM email accounts were not transferred over from their original broadband account. That leaves their old email accounts not attached to a live broadband account and vulnerable to deletion as part of VM's closure program.
To give you some background, VM stopped issuing new email accounts back in May 2022 and since then new VM customers have not had the option of having VM email accounts. With no new VM email accounts being opened and the closure of unattached VM email accounts that means the number of active VM email accounts is on a steady downward curve.
