Regarding Debarshi's proposed 3.12 feature:
https://wiki.gnome.org/ThreePointEleven/Features/WindowLiveMail
He and I already have it done. It was a simple patch to GOA [1] and a
simple patch to EDS [2]. Neither patch added any translatable strings,
and the only UI change is a new Mail switch in the Online Accounts panel
for Windows Live accounts.
Given all that, it seems kinda silly for this to sit on a shelf for the
next 6 months. I'm wondering if it would be acceptable to backport the
feature for GNOME 3.10.1?
