Is Exchange ActiveSync a 2 way sync with Reminders to Exchange Tasks and Exchange Tasks to iPhone Reminders, same with Calendar, Contacts, etc?
iPhone 7, iOS 11.1
Exchange ActiveSync is a protocol. And yes, the protocol allows for two way sync of information. However, depending on what your enterprise admins have setup and are allowing, they may restrict what information can be synced and in what direction.
The most common setup is for a bi-directional sync of information between the device and the back end service (Exchange, Exchange Online (Office 365), or IBM Traveler for IBM Notes / Domino).
While the iPhone tries to sync information from Mail, Contacts, Calendars, Reminders, and Notes. There may be limitations in what your back end systems can sync or translate.
You may need to check with your enterprise admins to determine what can and can not be synced with the iPhone based on what they support on the back end.
