There seems to be no granular policy in the Office 2016 Admin template to disable Cached Exchange Mode while also having the option to select it on the client side if needed.

Once the policy is applied, it will gray out the checkbox and users cannot select Cached Exchange Mode.

Is there some sort of registry hack that can be done to enable this?



Cached Exchange Mode is controlled by the following key; [HKCU\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\\13dbb0c8aa05101a9bb000aa002fc45a]

00036601 (REG_BINARY)

enabled value: 84 01 00 00

enabled with Public Folders/Favorites: 84 05 00 00

disabled value: 04 00 00 00
