The final version of Update Rollup 4 for Exchange Server 2007 SP1 (KB952580) is live and available for download. The rollup is marked as “v2” in the file name i.e. “Exchange2007-KB952580-v2-x64-EN.msp” to account for the accidental release of v1 via Microsoft Update on 9th September. This version of rollup will install over the “v1” mentioned above if you have installed a v1 when it was accidentally released, explains Exchange team.

This rollup fixes some bugs in Exchange Web Services (EWS), and introduces some behavior changes to EWS to allow customers and partners the flexibility to accomplish some key scenarios.  If you have written code against Exchange Web Services, we definitely recommend that you take a look at RU4. The following are the biggest changes that will be coming in the rollup:

  • Item IDs are now returned after MoveItem/CopyItem calls.
  • Unknown/unsupported item types are returned as Messages.
  • Updating tasks can now have correct behavior for Start and Complete Date values.
