    If I am ruing EX 2010 SP 2 AND I want to update to latest one SP 3 RU3
    should I go through all the SP2 RU’s then SP3 RU’s
    or I can go directly to SP 2 RU 6 then SP3

    Hi Paul.
    Tahnks for the advise.
    in Exchange Server 2010 SP3, Can I install directly this Rollup without install the previous rollup 2 ?

  3. Harold says:

    To apply Rollup 3 on SP3, will I need the SP3 files on the server? I read other users having issues with SP2 rollups.

    Lots of folks reporting outlook client “Category” issues after applying this Rollup and persisting in Rollup 4.

    Hi Paul, i have exchange 2007 SP3 and have installed rollup 11, 12, 13 and now having issues with connecting outlook anywhere. i can see that rollup 6 is missing, just woundering is it possible to install rollup 6 without uninstalling rollup 11, 12, 13. i believe rollup 6 is the best rollup for exchange as it doesnt have any issues with outlook anywhere.

    Please help

    • The URs are cumulative. You can’t install UR6 when you’ve already installed later URs.

      I don’t know of any known issues with Outlook Anywhere and any 2007 URs. I would suggest you troubleshoot the problem and if necessary contact Microsoft Support.

    Hello Paul,

    I installed SP3 and want to install UR13. I can run it, no problem. However, when I’m done, UR13 is not installed. Exchange shows Version 14.3 Build 123.4. It should say Build 294.0. Any ideas on what I can do?

    • The build number for Exchange 2010 servers shown in Get-ExchangeServer and in the Add/Remove Programs (or Programs and Features) control panel doesn’t change when an update rollup is installed. You can see the update in the Installed Updates view of the control panel though.
