I have searched and searched on this forum and google but cannot seem to find the answer to this problem.
I have an Exchange 2010 server working along side Exchange 2003. All mailboxes, public folders etc have been migrated and the only reason i havent removed the 2003 box is due to a core application not being compatable with Exchange 2010 yet.
I have created a new address list on the 2010 box but cannot add any contacts to it because when i choose the OU in AD that holds these contacts, i get the “You cannot specify the recipient contanier becaus legacy servers are detected”.
Does anyone know how i get round that? I know if the 2003 box was decommissioned completely i could run ADSI and remove it from the config list which is the normal fix for this error but i am still using this legacy server.
Any ideas greatfully received as im pulling my hair out.
