iOS device enrollment fails when an Exchange ActiveSync account exists on the device

Enrollment will fail on an iOS device that has a pre-existing Exchange ActiveSync account.  The user receives the following error message: "Profile Failed to Install: an identical Exchange account already exists."

The solution is to un-register or remove the account before enrolling against the NotifyMDM server.  The configuration profile will then successfully install and recreate the account.
