For you that still use Exchange 2003, Heads up!!
Exchange 2003 is now moved from Mainstream to Extended support on April 14, 2009.
What does this mean? Exchange 2003 is still supported for another 5 years.
Difference between Mainstream and Extended support can be found here http://support.microsoft.com/gp/lifepolicy
- Non-security hotfix support
- No-charge incident support
- Warranty claims
- Design changes and feature requests
As you can see there is not that much difference, but this is clear signal from Microsoft that Exchange 2003 life is coming to an end. This might be good time to start planning the upgrade to Exchange 2007 or Exchange 2010.
One way of still having full support is to purchase Extended Hotfix support.
Important to say is that you still have support when running Exchange 2003 as long as you pay for your incidents.
