it appears that Windows phone can't save any pictures from an email....
Really lame since I emailed some backgrounds that would look great on 8.1
Can't believe as good as 8.1 is that you can't even save a photo in an email to your camera roll or "saved" in the photo albums.
smh...
Yes I am reviving old thread, since it is already September 2015, and they never really care to fix or add this simple function to Outlook for WP. What a shame. And then they will wonder why they can't even compete with Android or iOS yet.
