We started using the Send Encrypted button with Outlook to encrypt email using the McAfee SaaS. Using this the message is sent and is encrypted correctly, but it is leaving a kind of stub message in the Outlook outbox that has to be manually deleted to get rid of it. The message subject and body are blank, but the To: and From: fields are filled out. We are an Exchange 2010 shop and I have tried it with both Outlook 2007 and 2013. I have also tried it on both a Window 7 x32 & x64 system.
Is anyone else seeing this problem? Support has not been much help on this issue.
