User Entries to Server List must be disallowed.
An XCCDF Rule
Description
<VulnDiscussion>This policy setting controls whether Outlook users can add entries to the list of SharePoint servers when establishing a meeting workspace. If you enable this policy setting, you can choose between two options to determine whether Outlook users can add entries to the published server list: - Publish default, allow others. This option is the default configuration in Outlook. - Publish default, disallow others. This option prevents users from adding servers to the default published server list. If you disable or do not configure this policy setting, when users create a meeting workspace, they can choose a server from a default list provided by administrators or manually enter the address of a server that is not listed. This is the equivalent of Enabled -- Publish default, allow others.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
