I have an odd issue that I haven't seen brought up here. I have my e-mail set up with my work exchange server. It works fine for the most part, except that it takes a while to push the messages. My old phone (Motorola Q) had nearly immediate push. With my Droid, it sometimes takes 15-30 minutes before a pushed e-mail will finally show up.
Has anyone else encountered this or know of a fix? Of course, I have double-checked that I have push selected for the account. I've read a number of examples of people not getting their e-mails, but never anything where they get the e-mails, but only after a while.
