I am syncrhonizing the notes, calendar, and contacts (not email) on my new iPhone SE (iOS 10) with an Exchange Server interface (AkrutoSync). It's not a full fledged exchange server. It simply presents an Exchange Server interface to the iPhone (or to an Android) to enable syncing with a Microsoft Outlook client running on a laptop or desktop.
Of the phones that can interface with it, iPhone is apparently unique in that the user cannot manually trigger a sync. Syncs occur every 10-15 minutes, I'm told. In my case, the iPhone connects to AkrutoSync over my home WiFi network.
Not being able to force a sync at will is a bit of a pain. If I create or delete an appointment on Outlook, I want to be able to synchronize at will. I don't want to wait an unknown length of time and hope that there was a sync. I might be headed out the door for some engagement.
Is it in fact true that iOS will not allow me to force a sync at will? If not, then how does one force a sync? Simply switching to away from an app (notes, calendar, contacts) and swithcing back doesn't do it. Neither does putting the phone to sleep and reawakening it.
