I traced my inability to back up text messages to a problem with my Microsoft account - "attention required."  I disabled the "Sync email" setting which others suggested, but noticed that the server name was m.google.com (I'm using a gmail alias for the MS account).  I deleted this, but the settings menu requires an address.  Any ideas?  I've tried m.email.live.com, m.mail.live.com, smtp.live.com, etc. but none seem to help.
I also uninstalled Skype for good measure
Note: Because I'm trying to save text messages, I'm reluctant to do a factory reset just yet.
