On this page, you will learn how to manually adjust the display name of a user certificate in the Windows certificate store.

This adjustment can be helpful if you use multiple functional e‑mail addresses in Outlook. As the RA‑Portal user certificates for functional e‑mail addresses do not contain a CN (Common Name), it is impossible to identify which user certificate belongs to which e‑mail address which makes configuring the digital signature via Outlook Trust Center difficult.

Please note that this change cannot alter the contents of the user certificate; it only changes how the certificate is displayed in local Windows applications.

To change the certificate’s display name, follow these steps:

1. Open Manage User Certificates (e.g., via the Windows search).
2. Under Personal > Certificates, select the desired certificate and open it with a double‑click.
3. Set the desired display name under Edit Properties > General and confirm with OK.

Now the certificate is clearly identifiable in Outlook Trust Center and can be configured for signing and encryption.
