I re-post the question as the advice from Arthur Xie originated from this thread: http://social.technet.microsoft.com/Forums/en-US/W8ITProPreRel/thread/c53a736d-ebde-4f80-95ef-c9b79c30dc01 I hope I am not polluting the forum, but I really would like to find an answer.
Installed and configured Microsoft Outlook 2010 on Windows 8 Preview. Import PFX into the CAPI store with high or medium level security into the Personal store. Use Outlook to send the secure massage to yourself. If Outlook runs without UAC elevation the compose window 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.
If user runs Outlook as administrator the password prompt dialog comes up and Outlook works in all the cases above.
Outlook should not have administrator privileges to access personal certificate store.
Over there is the additional info I provided to "Support Engineer" and didn't get any answer: http://answers.microsoft.com/en-us/office/forum/office_2010-outlook/outlook-configured-on-windows-8-required-elevation/c0090c0c-ab8d-4dea-9306-7d86ec2f9116
Could someone address the issue?
Thanks
