Please help! Upgraded Exchange 2007 to sp2 today and all upgrades (Hub/eCAS, Node1 and Node2) completely successfully. however I am rec'g an error from the Information Store.. the clustered mailbox needs to be upgraded before it can be brought online. When I try to rerun setup /upgradecms, it tells me the versions are the same. :o( what am I doing wrong here?? I have to have system up and running soon!
