Exchange 2003 on SBS 2003 but it's not out of the question for me to upgrade to Exchange 2010 if necessary. I have an Exchange 2010 server available I just haven't yet migrated the mailboxes over to it.
We recently got infected with the cryptolocker virus. I discovered that it arrived on the network through a phishing email with a link inside. This email had a very specific subject line which was targeted to look believable to this particular company, and it got past our anti-spam filters.
I don't know how many people received this email, but so far I've had to respond to four people who have gotten it so far and I'm worried that there are others who have also received it.
I won't be comfortable so long as this landmine is sitting in people's mailboxes.
Is there an efficient way for me as an administrator to search for and purge this email from ALL mailboxes?
