In this post, I will guide you through the process of installing Exchange 2013 Service Pack 1 on either Windows Server 2012 or Windows Server 2012 R2.

I have in my time as consultant installed a service pack on quite a lot Exchange servers, and before I’m installing a service pack, I also have a “checklist” which much be in place before I start the installation.


So what you need to do, is:

  1. Calculate approx. 1-2 hours for the installation depending on how fast your server is.
  2. Make sure you have a backup, also on your CAS servers.

    It might sound stupid or you think you have installed updates before and nothing happens so you don’t need it. But I have several times seen the update process crashed or stopped with an error, and if you are very unlucky the setup can’t revert the change and it might be in the process where all the old dll and exe files has been deleted. And then you have an Exchange which can’t start.

    In Exchange 2010 you most likely need the restore.

    I have experience the same with Exchange 2013 (the CU’s), and although it stops because of an error, I have not ones needed the restore, because the installer can recover from many errors (which is cool). But still don’t fool you self, make the backup before you start.

  3. Disable any antivirus programs, both file scanner and AW products with a plugin to Exchange.
  4. Uninstall the UM Language packs you might have install, and install the new ones when SP1 in installed.
  5. Reboot the server before your start, so that your don’t have any pending reboot, and the memory is “fresh”.
  6. Login with a user which is member of the “Domain Admins” and “Schema Admins” group. (the first server you update, will also update the schema)
  7. You should always start upgrading the Mailbox Server first, and then the Client Access Server.
  8. After you have downloaded service pack 1 double click on the file to extract it.

  9. Choose a folder for the extracted files

  10. Navigate to the extracted files and double click on setup.exe

  11. Click on Next

  12. Click Next

  13. Click on Next

  14. Select “I Accept…” and click Next

  15. Click Next to install the Service Pack.

  16. When it’s finish click on finish

  17. I always reboot the server after an service pack installation.
  18. After the reboot, check the event log and services.msc that your exchange is fit a well, and everything is running as expected.
  19. Install the UM Language pack if you uninstalled them (remember to use the UM pack that fits your new service pack)
