Hi, I have a question about Exchange 2007 and 2010 and their behavior in IPv6 environments. I have been able to find some information about the extend of support for IPv6 in Exchange 2007, according to the following article, does Exchange 2007 support IPv6 from SP1 and only in a IPv4/IPv6 environment, http://technet.microsoft.com/en-us/library/bb629624(EXCHG.80).aspx. And even though, Exchange 2007 has support for IPv6 from SP1, still some features are unsupported. And I would like to know if this is the same for Exchange 2010, but I have not been able to find clear information about that, so I was hoping some could give me some information about the extent of support for IPv6 in Exchange 2010. Regards, Bas

Isn't there anyone who has some information about the extend of support Microsoft Exchange 2010 has for IPv6? Bastiaan

Please see this article: http://technet.microsoft.com/en-us/library/gg144561.aspx

I read somewhere that both Exchange 2007 and Exchange 2010 supports IPv6 as long as the base OS is Server 2008 with IPv6 enabled.
