Disable Cached Exchange Mode on Terminal Server

Question

I am unable to find the administrative templates to disabled Cached Exchange Mode on a WS2025 TS I am deploying. Are these baked into some other area or is this no longer possible?

When I go searching for the templates I reach a 404 page from this URL: https://www.microsoft.com/en-us/download/details.aspx?id=49030&msockid=38de9113e6aa6e0531518724e7b66fc5

I recall needing administrative templates at some point, but am starting to wonder if I am misremembering that. Edit** after multiple days of the URL giving a 404 it is available again.

Hi Craig B,

Thanks for the update—and glad to hear the URL is finally resolving again.

You're absolutely right that administrative templates are typically required to configure policies like disabling Cached Exchange Mode, especially in environments like WS2025 Terminal Servers. The setting you're looking for is part of the Office ADMX templates, which include Group Policy settings for Outlook.

Cached Exchange Mode can be managed via Group Policy under:

Code

User Configuration > Administrative Templates > Microsoft Outlook [version] > Account Settings > Exchange > Cached Exchange Mode

If you're not seeing these options, it’s likely the Office ADMX templates haven’t been added to your PolicyDefinitions folder yet. You can download the latest templates from the Microsoft Download Center — now that the link is working again.

Once downloaded, copy the .admx files and the appropriate language .adml files (e.g., en-US) into:

Code

C:\Windows\PolicyDefinitions

Or, if you're using a central store:

Code

\\YourDomain\SYSVOL\YourDomain\Policies\PolicyDefinitions

After that, the Outlook-specific settings should appear in Group Policy Editor.

I hope my answer is useful for you.

Best,

Quinnie Quoc.
