  1. 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

  2. I am having an issue installing Update Rollup 2. Can I install Update Rollup 3 without Rollup 2 ?

    Thanks,

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

  4. Hi Paul,

    Have there been any reported issues with RU3 since its release on Monday?

    thank you.

  5. 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,

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

    Thoughts?

    Doesn’t look like it was addressed in UR5.

  8. 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
