I currently have Verizon DSL at my home and an established Verizon email address. I am moving in with someone who has Verizon DSL service. Is there some way to transfer my email account to be a sub account of someone else?
Verizon (per "policy") won't move a primary account to a sub account or vice-versa. If it's a sub account then no worries. If it's a primary... Maybe look into Verizon Your Domain?
