Hi. how can we get detail about from which date/time email forwarding is enabled for a user in exchange 2007 server.

Hi 

Are you looking for forwarding address parameter   for a user from when it was enabled. If that's the case there is no option in Exchange server  to check  from what time the forwarding was enabled.

Thank you, appreciate your quick response. If you find anything related to this at any point of time, kindly update me. As its very imp issue to me. :)

Not in Exchange 2007. Exchange 2010 has Admin Audit Log that keeps the track of anything changed in last 90 days by default when Exchange is installed...
