Donna Edwards who is a CRM MVP and pops up all over the CRM world commenting on forums, facebook, twitter and blogs always with useful bits of information tweeted a very interesting link a while ago about support dates for CRM versions.
but before I go into that I recommend you follow Donna via her twitter account – https://twitter.com/#!/edwardsdna

When it comes to supporting versions of CRM, I thought it was Microsoft’s policy to support the last two versions but Donna Edwards tweeted this Microsoft page which shows a date, which is useful information to give to your clients who are on Microsoft Dynamics CRM 4.
There is a Lifecycle Support Policy FAQ which is interesting and below I have copied the support dates from this original page. For my UK readers, these dates are in American format so it’s the 09/04/2013. Also with all the great enhancements coming to CRM 2011 soon, I think a lot of people will be upgrading
