I get the following error message when I try to open/view one particular email which I received recently from Outlook 2003 with all the latest service pack installed but I have never associated any certificates with Outlook. I have never had this problem previously. Neither did I changed any settings. What is the cause?
"Can't open this item. Your Digital ID name can not be found by the underlying security system."
No it doesn't affect the other emails. Only this one. – Lopper – 2009-12-14T05:38:19.317
My guess is someone accidentally sent you an encrypted email. You won't be able to read it without the proper key to decrypt it so I'd just delete it if you don't know the sender. – John T – 2009-12-14T05:42:26.483
