Cannot send PGP encrypted email with outlook
I have pgp desktop 10.2 , and Outlook 2010
In PGP desktop , I created a key for my own email address and added it to master key.
When I select 'encrypt message contents and attachments' , and send a email to myself , i get a error message "Microsoft outlook cannot sign or encrypt this message because there are not certificates which can be used to send from the email address xxxxxx"
What am i doing wrong?
