Harold Wong, Senior Technology Specialist, for Microsoft"s TechNet division has posted on his blog that he expects a customer preview version of the upcoming Exchange 2003 SP2 to be released within 2 weeks.
Microsoft announced in June that Exchange Server 2003 SP2 would include Mobile e-mail improvements, Better protection against spam and Advanced mailbox improvements. Some of the mobile e-mail improvements relate to the latest Windows Mobile 5 advancements. With SP2, users of Windows Mobile 5 will receive push"d email similar to that of Blackberry devices currently in use by many large corporations worldwide.
Harold will post to his blog once the CTP is live :)
