    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.
