when i am trying to install exchange 2010 on 2008 r2 member server, readiness check is failing at organisation prerequisites asking to modify AD with setup /prepareAD. when i ran prepareAD i get the following error.
Exchange organization name cannot be specified. There already exists an Exchange organization with name 'XXXX'.
i think this is because of my earlier unsuccessful attempts of installing exchange. can someone help me to get pass this. thanks
can i give the other name? or can i delete the organisation from ADSIedit?? what ever it takes, i need to get exchange up n running by this Sunday. cheers
