Exchange 2010, Outlook 2003 UDP notifications are back

has been criticised for appearing to be slow for clients, that's another way of saying that customers didn't rush out and update to the latest versions as they became available.

Outlook 2003 users would complain that messages would only appear on a minute boundary, and generally they hand held derives would receive new message notifications before they did.

Outlook 2003 used UDP notifications from the Exchange server to notify clients of messages as they arrived, note that the biggest impact here is users running in online mode,  not cached mode. Users with very large mailboxes running in online mode and/or terminal services users would have been the worst affected.

Fear no more, kb 2009942 releases detail available after the installation of Update 1 for Exchange Server 2010, presenting new configuration parameters in the registry.

That, along with the of Exchange 2010 service pack 2 and the GAL segmentation improvements coming later this year, along with a number of other posts on the Exchange teams website, has made it an interesting week in the Exchange community.
