Outlook calendar updates not updating
You can use this technology with any version of Outlook (2003, 2007, 2010, 20) as well as with any i Phone, including i Phone 5/5s, i Phone 6/6s/Plus and i Phone 7.
Exchange itself is usually not the root of the problem, the mail clients (Active Sync, i OS devices, Blackberries, i Cal) and their connectivity protocol tend to be the culprits. For instance, if someone accepts a meeting at 9am on an i Phone and a delegate declines it at am on a PC, but the i Phone is out of signal range and doesn't sync the meeting until say am., what happens to the meeting?
