Trying to install SP1 on my mailbox cluster. It's failing on Organization Preparation. Giving the error: The Name property contains leading or trailing whitespace, which must be removed. There's no error number, and it doesn't tall me what account is causing the problem. Any ideas, please?

Could you post the relevant lines from the ExchangeSetup.log file as well?

Found the problem. It was a 2003 recipient policy that had a trailing whitespace.

We have over 25 Recipent Policies how do we remove the trailing whitespaces: (&(&(&(& (mailnickname=*) (| (&(objectCategory=person)(objectClass=user)(!(homeMDB=*))(!(msExchHomeServerName=*)))(&(objectCategory=person)(objectClass=user)(|(homeMDB=*)(msExchHomeServerName=*)))(&(objectCategory=person)(objectClass=contact))(objectCategory=group)(objectCategory=publicFolder)(objectCategory=msExchDynamicDistributionList) )))(objectCategory=user)(company=BHB))) Thanks - Chris

I just did it manually by right clicking the policy and choosing rename.
