For the past 15 months, I've been using the stock email client on my droid razr to connect to my exchange account at work with push frequency, and everything had been working smoothly until yesterday. For some reason, yesterday the email client stopped pushing. I can manually check my email, but doing so for regular use is not feasible. After this problem started, I received notification about a system update & went through the update. Post-update, the push problem remains. Any suggestions?
