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┬áTerminal 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.
