Hi,

I am trying to create using makecert tool a self-signed certificate to use it with MS outlook, so I can encrypt the messages sent from my companys Ms outlook to my home Ms outlook.

My user name is jd, my domain name at work is lets say domain1.com. My e-mail is jd@blah.com.

I dont know why my real domain part (from control panel System/Advance system settings and Computer Name/Domain properties which is domain1) in my e-maiI part is different blah) thats been set by our IT people.

I have created a self-signed certificate like this:

makecert -r -pe -n "E=jd@blah.com,CN=jan" -b 01/01/2005 -e 01/01/2060 -sky exchange -ss my c:\temp\jdaleckiTyco.cer

I attach the certificate just created above to my e-mail account (which jd@blah.com) using menu File/Options/Trust Center/ Trust Center Settings/E-mail Security then Settings under both Choose buttons (in Change Security Settings dialog box) I select the above created certificate click OK/OK and OK again.

Now when I try to send a new message to lets say user X and clicking in the Option menu on the Sign button I get a message from Microsoft Outlook ver.2014 (,s office 2010):

Microsoft Outlook cannot sign or encrypt this message because there are
no certificates which can be used to send from the e-mail. Either get a new digital ID to use with this account, or use the Account button to send the message using an account that you have certificate.

Would you have any suggestions please,

Janusz

Hi Janusz,

Thanks for posting in MSDN forum.

This fourm is for developers discussing developing issue involve Outlook. Since this issue is more relative to end-user, I would like to move it to Outlook IT Pro Discussions forum.

The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us.

Thanks for your understanding.
