I have a Droid Razr MAXX HD that is synced through my company via corporate sync. The e-mail is running off Exchange 2010. The account syncs up fine, and I am able to send messages as normal, but after a period of time, one message will get stuck in the outbox and then I can't send any after, as they get stuck in the outbox because the other one is too. I can't go into the message because it says that it is sending. This is the only phone on my company's network that does this, and we have about 30 Android phones currently. As of right now, the only fix is to remove the account and re-add it, but I am looking for a solution to prevent it from happening again. If anyone could help, that'd be great, thanks.
