"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

In addition to rfekkes comments.

When you start the Service Pack installer and its doing its checks you may find that it brings up an error about the DataCollectionSrv.  If you do, stop the Windows SBS Manager service and then restart the Service pack installer.

Start the service after the service pack has completed its installation.

Once the Service pack has been installed check to see if you can access Outlook Web Access ok.  If you get a blank page then you need to run  updatecas.ps1 in the Exchange Management Shell.

Located here:
C:\Program Files\Microsoft\Exchange Server\V14\Bin

Might not happen but it will save you some time searching if you do.

And most importantly to echo what the others said, make sure you have a backup.
