Unable to setup Thunderbird using one User-ID and PWD combination, with multiple email addreses (Spectrum ISP).
I am trying to setup Thunderbird using one User-ID and PWD combination, with multiple email addreses (Spectrum ISP). I have executed the Profile Manager but it seems to use the email address provided as the account access User-ID. This is not working in my scenario. I need to provide to Thunderbird User-ID and PWD credentials once, and retrieve/send email for multiple email addresses. My ISP (Spectrum) supports multiple email addresses (up-to 5) that are associated with one User-ID and PWD.
