Installed Ru3 on Exchange 2010 SP1...have question on Outlook 2003 part of it

Posted on 2011-04-21

Installed RU3 this morning and everything seems to be working fine so far.  Main reason for installing this rollup was to address the UDP issue with Outlook 2003.  Our organization has a TON of Outlook 2003 users.

My question is that after I install this rollup is there any other steps I need to do?  I looked at article 2009942 and it says that after the applying the up date you need to :

After you install this update, you have to create the following registry subkey to enable the UDP notifications support feature:

Subkey location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeRPC\ParametersSystem

 Subkey name: EnablePushNotifications


Value: 1

Note If this registry key does not exist, or if its value is set to 0, the UDP notification support feature is not enabled.



So I went ahead and added that subkey as directed in the registry of the 2010 Exchange Server.  Do I need to do anything else?  If you read that article further it mentions that if you want to test if push notifications are working you need to add a subkey entry to the client computer that has Outlook 2003 as well.


Is this true?  Will I have to visit every PC that uses Outlook 2003 and add this registry subkey??


Thanks for any help or advice

    Accepted Solution

    The recommended order of installing the RU3 update for your Exchange servers is:
    1.Internet-facing Client Access servers
    2.Other Client Access servers
    3.Hub Transport servers
    4.Mailbox servers
    5.Edge Transport and Unified Messaging servers

    And You don't need to add this key to every desktop, You'll need to add this key to above specified servers only.
