UW Digital ID (Win) - Outlook 2010 & 2013 When you reply to or forward a signed or encrypted email Outlook automatically tries to sign or encrypt the reply or forward.

Outlook cannot sign or encrypt this message because there are no certificates which can be used to send from the email address

If there is no digital certificate installed on the workstation, Outlook cannnot send a signed or encrypted S/MIME message. In this scenario, if the registry value below is not configured, the following error message will be displayed.


"Microsoft Outlook cannot sign or encrypt this message because there are no certificates which can be used to send from the e-mail address '<e-mail address>'. 

Either get a new digital ID to use with this account, or use the Accounts button to send the message using an account that you have certificates for."


As a workaround, you can use the following instructions to make Outlook 2010 and 2013 not attempt to automatically sign or encrypt a reply or forward that was signed or encrypted.
  1. Save the following file to your desktop: Outlook_Fix.reg
  2. Right click on the file and choose "Merge"
  3. Hit "ok" to ignore registry prompt
  4. Exit and restart Outlook

Another option is for the individual message that you are seeing the error you can un-check the sign and or encrypt option(s) and then click send.
Within the email message window under the "Options" Tab or Ribbon in the Permission section you will see two Mail Security icons, the red signing icon and the second is the blue encrypting icon make sure both are un-selected.
Note: this will not prevent Outlook from attempting to automatically sign or encrypt replies or forwarded emails in the future.
