# Signaturprüfung in Outlook

This source provides instructions on how to verify the authenticity of digitally signed emails within Microsoft Outlook. It emphasizes the visual indicators of a valid signature and the process for inspecting certificate details to ensure the sender's identity.

The documentation specifically references the "seal" (Siegel) icon as the primary indicator of a digital signature. According to the source, an email is considered authentic if the seal icon is present and the sender's email address is correct.

The source also describes two levels of information access:
1. Clicking the seal icon provides basic signature information.
2. Using the "Details" button allows the user to view the full digital certificate.

Note: The source URL explicitly mentions Outlook 2010, which may imply that the UI descriptions are specific to that version.
