I am having the same problem and more. Last weekend my itunes wouldn't load. I synced my phone to my laptop and the problem was fixed, but now my email is all screwed up.
1. When I open my email, it automatically goes to my gmail inbox.
2. I try to send messages to the archive box, but it unchecks the items before I can send them. I can usually send them on the second try, though.
3. When I read messages from my outlook on my phone, they do not show up as read on my computer.
4. The screen freezes for texts, emails, and phone calls.
I'm hoping that since I'm having some of the same issues as you, the same fix will work for both of us.
I read several posts in the last few days and tried multiple things like deleting the accounts and re-adding them. I changed settings. I restored my phone to factory settings.
Any help is appreciated!
Thank you
