I been trying to find a solution to this problem ever since Windows 8 was released to the public on October 26, 2012.
I installed and configured Microsoft Outlook 2010 fresh (no importing of profiles or old PST) on Windows 8. Import PFX into the CAPI store with high or medium level security into the Personal store. Use Outlook to send the secure or signed massage to yourself.
Outlook will hang during send of e-mail with sign and encrypt option. It will hang as well while trying to read encrypted message. Outlook will hang during start up if the first message in Inbox is encrypted.
Outlook should not have administrator privileges to access personal certificate store.
I posted on Microsoft Community site but got nothing:
Can't Sign or Open Encrypted Messages - Outlook Not Responding
I tried calling but was forced on dead end path for a $105 support cost.
The current workaround is to use Windows Live Mail Desktop for Windows 8 but most of my data is on Outlook.
So please help.
