I've looked high and low to find a resolution to this on the stock rom.

If someone is able to provide a work around without mentioning 3rd party apps like touchdown I would be very grateful. At work we run Exchange 2010 and there are a number of users with android based phones who are now left high and dry. Some are desires, some are nexus ones however I believe I am the only one running 2.2

I am open to putting a rom etc however would need concrete evidence that this is a genuine option and not a 'might work' scenario.

The IT team are also open to suggestions that would allow android phones to sync up without sacrificing corporate security.
