    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?

    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

    Hi Paul,

    I have some concerns…can you clarify me.

    My set is running exchange 2010 sp3 ru2,
    CAS/Hub is running on one server(windows server 2008 R2)
    2 Mailbox servers are running two physical machines. They are part of DAG

    I just want to add a new cas role on existing mailbox using exchange 2010 sp3…then what is my roll up version on cas role on existing mailbox server.

    Thanks
    Siddu

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

    Thoughts?

        The Exchange Team blog has some discussion of this issue. The problem is that users are unable to sort by Category. It sounds like it only affects users in Online mode. If Outlook is set to Cached mode, then it’s not a problem.

        1. Jeff G

          A client-side workaround for the bug isn’t quite a bugfix or hotfix for the categories issue.

          Lets say 20% of your users with online mode, they would be impacted unless you switched them to cached mode or updated the folder view for each mailbox. So the real news is we’re waiting for SP3 Update Rollup 5 (March/April?).

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

    Thanks,

    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
