When i download a certificate from CA authority, I get a certificate with SHA! encryption algorithm and when I install the certificate on some stations, the algorithm is forced to become MD5 and there is no SHA1 which makes the encryption fail.

How can I add the SHA1 algorithm within the outlook?

It is not a common way. Did you check under Tools/Options/Security/Parameters (default parameter), look to the field 'Hash algorithm'. This field is set to MD5 or SHA1 ? If it is set to MD5, set it to SHA1 and then encryption should not fail.

Hope it helps

I did check that and my problem is there, I have only the MD5 options and there is no SHA1 option. I need a way to add the SHA1 option.

Thank you
