Hi Experts,

on my EXCH2007 I have seen some Rollups not installed, like ROLLUP 2 and 7.
Does a new Rollup pakage include all previous updates ?

You should be fine to install the rollups. The service packs include all the previous rollups prior to it so it is really like a line in the sand for updates.

Update Rollups are cumulative and only the latest one needs to be installed. In this case UR 21 for Exchange 2007 SP3 is the latest; and is only one of 2 currently supported URs (along with SP3 UR20).  Any other (older) UR can be safely disregarded.

"For Exchange 2007, each update rollup package is cumulative. For example, if you apply Update Rollup 4 on a computer that is running Exchange 2007, you receive all the fixes in that particular update package together with all the fixes that were released in all earlier update rollup packages. In this example, you receive all the updates that were released in the Update Rollup 1 through Update Rollup 4 packages."
