Here it comes! All Exchange Pros around have long been anticipating this release and now it is RTM.
Most of the features of SP1 were described earlier, and Microsoft released a beta of the mail server’s service pack in June at its Tech-Ed event in New Orleans. This first service pack features improved e-discovery and e-mail management capabilities for IT pros. Those capabilities are enabled, in large part, because Exchange 2010 uses a new “Exchange archive” approach for e-mail storage that differs from the traditional .PST storage approach.
The feature list and additional details are available here -
This is really excited and I’m looking forward to see it rolling out into the production environment soon.
SP1 for Exchange 2010 can be retrieved via the Microsoft Download Center here (a 522 MB download).
Happy installation/upgrade, Exchange Bros!
Just upgraded my home Exchange lab to Exchange 2010 SP1 Beta. The upgrade went smooth, no problems so far and I’m really excited to try those
