Outlook 2010 – Disable Cached Mode with Group Policy


KB ID 0000507 Dtd 20/09/11


I got asked how to do this today, a client has a number of roaming users (teachers) who don't like waiting for Outlook to create a local copy of the mailbox each time they log on. To be honest as they have Exchange 2010 they would be better using the feature rich Outlook Web App (OWA) rather than the full client if they need to move around so much but hey, I was asked.


1. To do this you need to use a custom administrative template, thankfully Microsoft have them pre written go here to down load the administrative templates.

2. Download and extract the templates to your domain controller. Start > Administrative tools > Group Policy management console > either create a new policy and link it to your USERS or edit an existing policy.

3. Navigate to:

User Configuration > Policies > Administrative Templates

Right click > Add/Remove Templates.

add a custom adm

4. Add > Navigate to the folder where you extracted the templates > ADM folder > en-us folder (change depending on your locale) > Outlk14.adm > Open.

add a custom adm

5. Now Navigate to:

User Configuration > Policies > Administrative Templates > Classic Administrative Templates > Microsoft Outlook 2010 > Account Settings > Exchange > Cached Exchange Mode

Locate "Use Cached Exchange Mode for new and existing Outlook Profiles"

add a custom adm

6. Set the policy to "Disabled" > Apply OK > Close the policy editor.

add a custom adm

7. Then get the clients to log off and back on again, wait a couple of hours, or manually run "gpupdate /force" on them.
