When I set up Xtra mail on my iPad, I just type in my xtra email address and password, and Yahoo as the provider and it works.

WHen I try the same method on my Windows phone - it does not work. Does anyone know why (or is it temporary probelm related to recent down time)?

Also, how do you set it up, so that the sent mails are stored on the mail server so if I send an email from (say) my iPad email client, then When I access my Xtra mail using Outlook on my Windows phone, I can see the email in the sent folder.

I had not been able to sync my Xtra sent folder across multiple clients / devices since they switched to Yahoo a few years ago. [The inbox sync's fine].
