Exchange 2007 SP3 Rollup 11

exchange2007logo2[1]Today the Exchange Team released Rollup 11 for Exchange Server 2007 Service Pack 3 (KB2873746). This update raises Exchange 2007 version number to 8.3.327.1.

Here’s the list of changes included in this Rollup:

  • 2852663 The last public folder database on Exchange 2007 cannot be removed after migrating to Exchange 2013
  • 2688667 W3wp.exe consumes excessive CPU resources on Exchange Client Access servers when users open recurring calendar items in mailboxes by using OWA or EWS

In addition to these fixes, this Rollup also includes a fix for the security issue described in Microsoft Security Bulletin MS13-061.


  • When running ForeFront Protection for Exchange, make sure you disable ForeFront before installing the rollup and re-enable it afterwards, otherwise the Information Store and Transport services may not start. You can disable ForeFront using fscutility /disable and enable it using the fscutility /enable command;
  • If you want to speed up the update process for systems without internet access, you can follow the procedure described here to disable publisher’s certificate revocation checking;
  • Rollups are cumulative, i.e. they contain fixes released in earlier update Rollups for the same product level (RTM, SP). This means you don’t need to install previous Rollups during a fresh installation but can start with the latest Rollup package.
