after updating to 4.4.2, I was able to send email from two separate accounts but neither would receive any. After 2 hours of messing with settings and talking with AT&T support (nice but of no help), and sitting on hold with Samsung support with no answer, I deleted both email accounts and re-created them. This was the only thing I was able to do to solve it, but at least it worked. Save yourself some time and grief and just delete the account and re-create it.
