If what you are trying to do is prevent Cached Mode in Outlook then use the below GPO. The below instructions assume you are using Outlook 2010 as you haven't specified which version of Outlook you want to do this for. I will also assume you have already loaded up the Office ADM/ADMX templates in GPMC:

- Open the Group Policy Management Console
- Drill down to User ConfigurationPolicies > Microsoft Outlook 2010Account SettingsExchange > Cached Exchange Mode
- Disable the following settings:
- Cached Exchange Mode (File | Cached Exchange Mode)
- Use Cached Exchange Mode for new and existing Outlook profiles
- Go back one level to User ConfigurationPolicies > Microsoft Outlook 2010Account SettingsExchange
- Enable the following setting:
- Do not allow an OST file to be created

To turn of the cached mode in Outlook Exchange, follow the given path

File >> Account Settings >> Account Settings >> Select the account >> Change (click on it) >> Uncheck “Use Cached Exchange Mode” under the Offline settings.

After disabling the cached mode in Exchange, restart Outlook to see the difference. You can also input the “0” as NoOst dword value, but it will only disable entire section of emails.

Disable Via GPO

In Group Policy, you can find the settings under User Configuration\Administrative Templates\Microsoft Outlook 2013\Account Settings\Exchange\Cached Exchange Mode. The OCT settings are in corresponding locations on the Modify user settings page of the OCT.
