Answer 1

I had this issue and this was what worked for me, I was using the "hotmail" option though.
1. go to settings
2. go to mail, contacts, calendars
3.delete your email from device
4. click "add account"
5. there should be different account options, chose "other"
6. chose "add mail account" and do so
You  should be able to send now, but you might want to check how it updates.  Certain email options used "push"  which lets you know you have a new  email the moment you get it, much like a text message. "Other" only  allows you to have "fetch" which updates every selected amount of  mintues, and "Manual" which does exactly what it says.
7. It should return you to the mail, contacts, calendars page. Press "Fetch New Data"
8.  there will be a list of when it will update your email. The less it  updates, the easier it is on battery life. There is a manually option.
9. If you want to use the actually "Manual" Update schedule then press "Advance" then your account.
10. There you can chose "Fetch" (which I suggest if you use email a lot and there is a manual option there anyways) or "Manual"
I really hoped this helped! If it did then well....awesome.
