Seven Beta will do this. It can also push your other accounts but I would limit it strictly to your work email. The memory utilization on the Seven PPC client with 3 email accounts is ridiculous so I only use it for work, and it stays reasonably under 1mb of ram.

As for the connector options you can download the standard (Workgroup Edition) which relays messages, appointments, contacts to your mobile or you can use the OWA option. The OWA does not require you to have any special access and it hits the webmail page as if it was a browser.
I would recommend running the connector on the desktop and turning your workstation off as needed. I'm staying under the radar as well and this seems to be the safest, most reliable solution.
As for the alternatives, I've found that emoze is nice but Seven push is amazing. I really like the 2 way sync for my appointments and contacts.
