How to disable Exchange cached mode in Outlook on the Terminal Server.

Hi,

Today I will show you how to disable Exchange Cached Mode in Outlook on Terminal Server. Unfortunately we can’t do it using GPO because “Use Cached Exchange Mode for new and existing Outlook profile” only exists in the User tree.

Open regedit

Go to: HKLM – > Software -> Policies -> Microsoft -> Office -> 15.0 -> Outlook -> OST and create dword NoOST -> give value 2.

HKEY_LOCAL_MACHINE/SOFTWARE/Policies/Microsoft/Office/14.0/Outlook/OST

For outlook 2010 change 15.0 to 14.0.
