Do not sync in Cached Exchange mode when users click Send/Receive or F9

By default, when users click Send/Receive or press F9 for Cached Exchange Mode accounts, Outlook synchronizes with the Exchange server. When this setting is enabled, clicking Send/Receive and pressing F9 do not synchronize with Exchange unless only one folder is being synchronized. Users can continue to use shift-F9 to synchronize the current folder.

Supported on: At least Windows 7
