I'll check all the other questions and get back to you asap

one.com are using an unconventional configuration.

Is the gmail account broken as well?

I presume you can get on line in other ways? For instance, you are posting here so you have internet and www access?

This page https://www.one.com/en/support/guide/mail/setting-up-windows-mail suggests 465/SSL for smtp. Do you know where the unusual 2525 setting came from? Are you using any email scanning software that inserts a proxy?
