Got a weird problem.
Migrating from Exchange 2003 to Exchange 2010 to achieve a co-exisiting situation on the domain. However, I am hitting a bit of a problem. My Domains and Trusts prog. states my Forrest Functional Level is 2003 - I have a minimum spec of Ent. Servers of 2003 SP2 on the domain. However, when I run : setup /PrepareLegacyExchangePermissions on the new proposed EXCH 2010 server ... I get an error stating that the Forrest Functional Level needs to be at 2003 ... which it is. Anyone came across this before.
Any comments would be appreciated.
