Ensure 'Suppress external signature services menu item' is set to 'Enabled'

高レベル 1自動office

説明

This policy setting controls whether Outlook displays the "Add Signature Services" menu item. The recommended state for this setting is: Enabled. Rationale: By default, users can select Add Signature Services (from the Signature Line drop-down menu on the Insert tab of the Ribbon in Excel, PowerPoint, and Word) to see a list of signature service providers on the Microsoft Office Web site. User setting: the audit checks HKEY_USERS\<SID>\SOFTWARE\Policies\Microsoft\office\16.0\common\signatures:suppressextsigningsvcs (REG_DWORD) in every loaded user hive (S-1-5-21-*) and is compliant when each holds 1. It prints 'no-user-hive-loaded' (FAIL) when no user profile is loaded, so scan while users are logged on.
