My iPhone 3g occasionally can't connect to the Microsoft Exchange server. My AOL account consistently gets email with no problems. Outlook and OWA on my computer get emails without issue as well. Usually, it takes 1 to 3 hours before my IPhone connection to the server is restored. This just started happening in the last month and happens several times a week. I have deleted and reentered the exchange account into my IPhone more times than I can count. Why is this happening? Microsoft has no idea. Thanks in advance.
