Starting mid-November 2024, Outlook on iOS will support specifying iOS build numbers in ActiveSyncDeviceAccess rules. Organizations can update existing rules to use this feature, but it's not mandatory. Review the 'New-ActiveSyncDeviceAccessRule' documentation for guidance.
We're making some changes to the ActiveSyncDeviceAccess rule DeviceOS parameters for Outlook on iOS.
Starting in mid-November, we will start supporting the operating system build number in addition to the operating system version number.
When this will happen:
General Availability (Worldwide, GCC, GCC High, DoD) We will roll out this change in mid-November 2024
How this will affect your organization:
You are receiving this message because users in your organization may be subject to ActiveSyncDeviceAccess rules on their Exchange mailbox.
Administrations will now be able to specify the iOS operating system build number with the DeviceOS parameter as "iOS X.X.X XXXXX" like "iOS 17.5.1 21F09", when this change is implemented.
Administrations who have pre-existing ActiveSyncDeviceAccess rules will not be affected by this change. If you want to take advantage of this new capability you will need to update any existing rules.
What you need to do to prepare:
When this change takes effect, you will not need to do anything. If you want to take advantage of this functionality you need to update your ActiveSyncDeviceAccess rules or set new ones.
