Microsoft has released Update Rollup 6 for Exchange Server 2007.  The update includes a critical security fix outlined in bulletin MS09-003.

The full list of fixes can be found here, and the download files are here.

I’ve updated our Exchange servers here last night and it went smoothly, no problems encountered.

Make sure you read the release notes to be aware of the main issues encountered with Exchange update rollups:

  • customised OWA interfaces (backup your customisations as they will be overwritten by the update)
  • CAS-proxy deployments (update the internet-facing CAS first)
  • managed code services not starting after update (permit access from the server to the Microsoft CRL)
