During the installation of MailStore Server, an SSL certificate is generated which MailStore Web Access/Outlook Add-In can use for access via HTTPS. Since the certificate is issued to the server name MailStoreServer and does not come from a reliable certification authority (CA), it is not trusted by the client side.


Because of this, the following warning message is displayed when calling up MailStore Web Access via HTTPS (SSL):


One option for resolving this issue is to make the server on which MailStore Server is installed available under the host name MailStoreServer (e.g. by adding and A- or CNAME record in the DNS) and installing the certificate in the container of trustworthy root certification authorities on the clients. Because these installations involve a relatively high administrative overhead, MailStore Server provides the option to use signed certificates of your own company CA or certificates of a public certification provider (e.g. VeriSign, eTrust etc.).

Um MailStore Server für die Verwendung eines eigenes Zertifikats zu konfigurieren, gehen Sie wie im Folgenden beschrieben vor.

Installing the Certificate

  • Log on to the server as administrator.
  • Click on Start | Execute.
  • Execute the command mmc.
  • Select File | Add/Remove Snap-In | Add| Certificate.
  • Select Local Computer Account and then Local Computer.
  • Click on Finish and close any open dialog windows.
  • In the management console, select My Certificates | Certificates.
  • Right-click on the folder Certificates and select All Tasks | Import.
  • Folgen Sie den Anweisungen des Assistenten und wählen Sie die Datei aus, welche das Zertifikat und ggf. den privaten Schlüssel enthält.
  • Wählen Sie auf der Seite Zertifikatsspeicher den Container Eigene Zertifikate aus und schließen Sie den Assistenten anschließend ab.
  • Das Zertifikat wird nun im Container Eigene Zertifikate angezeigt.
  • Zur Kontrolle öffnen Sie das Zertifikat über einen Doppelklick und vergewissern Sie sich, dass Sie über den privaten Schlüssel für das Zertifikat verfügen.

Using the Certificate with MailStore Server

  • Open the MailStore Server base configuration.
  • Select Web Access/Outlook Addin and click on Configure HTTP/HTTPS Access.
  • Click on Select Certificate and choose the new certificate.
