Chapter 4 Infrastructure and integration 28
Microsoft Exchange Autodiscovery
iOS and OS X support the Autodiscover service of Microsoft Exchange Server 2007 or later. When
you manually congure an Apple device, Autodiscover uses your email address and password to
determine the correct Exchange Server information.
For more information, see Autodiscover Service at the Microsoft website.
Microsoft Direct Push
Exchange Server automatically delivers email, tasks, contacts, and calendar events to iOS devices,
provided a cellular or Wi-Fi data connection is available.
Microsoft Exchange Global Address List (GAL)
Apple devices retrieve contact information from your organization’s Exchange Server corporate
directory. You can access the directory while searching in Contacts, and it’s automatically
accessed for completing email addresses as you enter them.
Note: iOS 6 or later supports GAL photos (requires Exchange Server 2010 SP 1 or later).
Set out-of-oce reply message
iOS 8 supports the use of automatic message replies when the user is unavailable. The user can
also select an end date for the replies.
Calendar
iOS 8 or later and OS X Mavericks or later support the following features of Microsoft Exchange:
•
Wirelessly create and accept calendar invitations
•
View an invitee’s calendar free/busy information
•
Create private calendar events
•
Congure custom repeating events
•
View the week numbers in Calendar
•
Receive calendar updates
•
Sync tasks with the Reminders app
View the Exchange identier
iOS 8 lets the user see the unique device identier that’s seen by the Exchange Server, called
the Exchange Device ID. This is useful when the Exchange Server the user connects to requires
devices to be whitelisted before access is allowed. They can supply this identier to you in
advance. The Exchange Device ID changes only if the device is restored back to factory settings.
It won’t change when upgrading from iOS 7 to iOS 8. To view the Exchange Device ID on an iOS
device, tap Settings > Mail, Contacts, Calendars > Add Account, then tap Exchange.
Identify iOS versions with Exchange
When an iOS device connects to an Exchange Server, the device reports its iOS version. The
version number is sent in the User Agent eld of the request header, and looks like Apple-
iPhone2C1/705.018. The number after the delimiter (/) is the iOS build number, which is unique
to each iOS release.
To view the build number on a device, go to Settings > General > About. You’ll see the version
number and build number, such as 4.1 (8B117A). The number in parentheses is the build number,
which identies the release the device is running.
