NOTE:
Some operational environments may elect to allow use of RSS feeds integrated into Outlook, provided there is a mission need and the network environment meets the following criteria:

- Both the website issuing the RSS feeds and the Outlook email client have an available network path to each other.
- Neither the website issuing the RSS feeds nor the Outlook email client has a network path to the public Internet.

An example of such an environment would be a closed lab or other deployed network where the requisite signoffs, artifacts, and network documentation demonstrate that the public Internet is not available to the Outlook client, preventing unauthorized RSS subscriptions being accessed by users of the Outlook client.

If the environment meets the above stated criteria, this requirement is Not Applicable.

For all environments where the Outlook email client has access to public Internet websites, RSS integration into Outlook is not permitted, and should be validated as follows:

The policy value for User Configuration -> Administrative Templates -> Microsoft Outlook 2013 -> Account Settings -> RSS Feeds "Turn off RSS feature" is set to "Enabled".

When this policy setting is enabled, the RSS aggregation feature in Outlook is disabled.

Procedure: Use the Windows Registry Editor to navigate to the following key:

HKCU\Software\Policies\Microsoft\Office\15.0\outlook\options\rss

Criteria: If the REG_DWORD value for "Disable" is 1, this is not a finding.
