    I’ve only just applied SP3 on to my Exchange 2007 server. Can I just jump straight to RU7? Or would I need to apply previous ones first, then RU7?

      They are cumulative, so you can just go straight to the latest one.

        Thanks Paul…
        OK well here goes… fingers crossed that this UR doesn’t have any major bugs later down the track like the the one in SP3 UR3.
