I have a user that is having issues sending a file that needs to be encrypted to anyone outside the company. The encryption tool being used is S/MIME.
When she attempts to send the file via outlook to someone outside the company, she receives the following error message:
"Microsoft Office Outlook had problems encrypting this message because the following recipients had missing or invalid certificates, or conflicting or unsupported encryption capabilities"
The weird thing is that she is the only one having this issue as two others using the same tool are having no issues what so ever. IT should be known that all systems are win7 /w office 2007.
One of the guys in our security group who installed the program thinks outlook should be reinstalled, but says he really isn't sure what the issue is.
Any help on this would be appreciated.
