I have installed the Exchange Quota Message Service, and when I tried to manually start quota maintenance it tells me RPC server unavailable. can anybody point me in the right direction here? I have googled the error but cannot seem to find anything that corresponds to this situation. I suppose it is possible this error is unrelated to me installing the Quota Message service, and I did get an email last night stating my mailbox was over the limit. I ran a netdiag and saw no errors. gary
