Good ol' AC. Have been dealing with this issue for a week, and had been blaming my company for it (should've known to check here.) My company requires us to change passwords every 90 days. I did not experience any problems with my Exchange email (the only one I use the native client for) until after I changed the password; then it just stopped working altogether. The coincidence of the timing - in addition to past issues on a prior smartphone - led me to assume it was an issue with our company's email servers. But, when they couldn't solve the problem, I began searching online and found this thread. I've tried all the usual tricks - including nearly all those mentioned in the very long thread over at Verizon Communities; still no love. As of yesterday, I began using Touchdown for now (complies with my company's security requirements), but it is far less than ideal, and I'm not happy that I'll have to start paying for it if this issue isn't resolved in 30 days. I'm mostly pissed because this update was apparently pushed to my phone without my consent. I never install updates until I've researched them, and certainly would not have installed this one. It's completely hobbled my phone for business use. Anyway, I'll keep my eye on this thread and the one over at VZW and hope for a fix sooner rather than later. Either that, or release KitKat, though I understand it has its own issues. *sigh*
