  • 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.
  • If you got a DAG and want to properly update the DAG members, check the instructions here.
  • Rollups are cumulative per service pack level, 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.

As with any Hotfix, Rollup or Service Pack, I’d recommend to thoroughly test this rollup in a test and acceptance environment first, prior to implementing it in production.

  1. Thanks for the info Michel.
    I have a question. We have 4 CAS in our environment. I installed the Rollup on each server and 3 of the 4 had no issues. One of them(let’s call it CAS1) lost all the images in the themes folder. I corrected this by copying them from one of the other servers. Then I discovered that when hitting CAS1 to access OWA a blank white screen was encountered. I was able to correct this by going into IIS and re-enabling ‘Anonymous Authentication’ on the correct version number. But now when accessing OWA via CAS1 nothing responds. When I click on to select and read messages nothing happens. Has anyone seen this behavior before and if so what’s the fix?




  2. We have the same issue (on our single SBS2011 server) , no images when accessing webmail login page and once logged in, complete empty/white page.
