I've been asked to recover a Exchange 5.5 server which has had some of the Exchange log files deleted by an anti virus package and they don't have a backup! Is this possible? I ran eseutil /g against the private and public stores, and no errors were reported. But when I try to start the information store I get "The Microsoft Exchange Information Store service terminated with service-specific error 4294965485" which is a file not found error. Alternatively as they seem to keep most files locally in pst files rebuilding it with a blank database wouldn't be too disastrous. What is the easiest way of doing this? TIA Andy
