    I have a couple of users who are PA's to senior staff using Outlook 2010. Problem I have is that when Outlook opens two mailboxes that each contain multiple folders we experience various issues revolving around Event ID 9646. I know there is a reg hack that increases the folder limit but I'm loathe to try this without exploring further options.

    Lets take one of our users for example. They have 648 folders created under their Inbox folder. I want to know if it would make a difference if we were to move these folders to the root of the users mailbox? And if it would be worth splitting them in to 5 separate folder to have a structure similar to this:

    • A to D (relevant subfolders under this main folder and so on for the rest)
    • E to I
    • J to N
    • O to S
    • S to Z

    This would be a huge one time pain for the user in question and only worth doing if:

    1.       it stops future 9646 server errors
    2.       reduces load on the server

    Can anyone confirm or perhaps suggest a different way to cut this cake? And no, the users will not consolidate their folders to reduce them – I’ve already asked!

    1: No (You will have to make that registry change to get it fixed)
    2: Not much (I don't think so)

    What is the exchange version you are running?

    Hi

       You can modify value of regedit.

        HKLM\System\CurrentCntolSet\services\MSExchangeIS\ParameterSyste

       Create the Dword by the name

       MaxObjsPerMapiSess

    Set the Value to: 800 or 1000.

    Since I already stated I knew about the registry fix and nobody else has offered an alternative I consider this 'answered' by myself!

    If anyone would like more detailed info about the Exchange Store Limits and the relevant registry setting, this link will give you all you need to know:
