Hi I have an Exchange server and an application that relies on Exchange events being fired on a folder when items are added/deleted. This has been working fine, but now the events do not appear to be firing. I have checked that permissions on the mailbox and the event handler in COM are fine, and there is still a SystemMaibox on the server that looks OK (although how do I tell?) The only change of significance that I can think of is another Exchange server was installed in the same domain. Any suggestions as to what might prevent event from firing on a mailbox folder in Exchange would be very gratefully received. Any suggestions on whee to look to verify if Exchange events are firing would also be gratefully received (WMI?) Regards Mike
