The text file should look like:
[encoded data]

Note: Make sure there are 5 dashes to either side of the BEGIN CERTIFICATE and END CERTIFICATE and that no white space, extra line breaks or additional characters have been inadvertently added. Save the file with the extension of .cer.

Or, download the certificate as per the instruction in the following solutions:

Installing the certificate with the Exchange Management Console:

  1. Start the Exchange Management Console: Start > Programs > Microsoft Exchange 2010 > Exchange Management Console
  2. Select "Manage Databases", and then select "Server configuration"
  3. Select the certificate from the center menu (listed by its Friendly Name), and then select "Complete Pending Request" from the "Actions" menu.
  4. Browse to the certificate file, then select Open > Complete

    Note: Occasionally Exchange 2010 will show an error message stating "The source data is corrupted or not properly Base64 encoded." Please ignore this error. Often times the installation is successful in spite of the error message.

    Press the F5 key to refresh the certificate and verify that it now says "False" under "Self Signed". If it still shows "True", the wrong certificate may have been selected or the request may have been generated on a different server. To resolve this issue, create a new CSR on this Exchange server and reissue the certificate.
  5. To enable the certificate, go back to the Exchange Management Console and click the link to "Assign Services to Certificate"
  6. Select the server from the list provided, then click Next
  7. Select the services for which the certificate must be enabled then click Next > Assign > Finish

    The certificate is now Installed and enabled for use with Exchange.
