exchange 2003 (3 domains: 2 native and 1 mixed) to exchange 2007

i have one forest with three domains, i have two domain in native mode and
one in mixed mode.

I want to install exchange 2007 in a computer join in one of the native
domains, but we have got users with mailbox in the three domains , i read
that for to install exchange 2007 the domain must be in native mode, but
almost users are in the mixed mode. It could be possible? Now i have a
exchange 2003 organitation.

Thank you and sorry for my english

Hi,

See this: "For all domains in the Active Directory forest where you will
install Exchange 2007 or that will host Exchange 2007 recipients, the Active
Directory domain functional level must be Windows 2000 Server native or
higher"

Hi,

That is correct, the domain must be native.
