This answer is a bit delayed, but may still be useful.
I recommend you to consider the Agile GrinMark to Exchange Synchronizer (GESync). It provides server-side integration between Salesforce and Exchange. Integration includes two-way synchronization of Contacts, Accounts, Leads, Meetings, Calls, Tasks; Archiving emails; special scenarios to replicate and create items like Opportunities and Cases from your email client. This solution works without any client-side plugins. No need for additional configuration of standard mobile or desktop email clients (Outlook, Entourage, Mac Mail, iPhone, iPad, Android, Windows Phone, Blackberry, etc.).
Microsoft Exchange: 2007, 2010, 2013, Office365
Free trial version is available so you can try GESync before making a decision.
If what you need is one-time synchronization, then trial mode may be enough to get required results.
