If your following my posts you may notices I touched on a bug with Exchange 2013 SP1 before even posting about this update. That’s because I started to write this and didn’t yet finish; better late than never; I guess!

The following enhancements have been made with the release of Service Pack 1 for Exchange 2013

  • Support for running Exchange 2013 SP1 on Server 2012 R2.
  • Support for Windows Server 2012 R2 Domain Controllers and Windows Server 2012 R2 Forest and Domain Functional Level.
  • MAPI over HTTP. More information on MAPI over HTTP here. Note that MAPI over HTTP requires Outlook 2013 SP1; you can download Office 2013 SP1 32-bit version here and the 64-bit version here.
  • DLP policy tips for OWA.
  • Add custom document types to DLP using fingerprinting technologies.
  • Cmdlet logging in Exchange Administrative Console.
