Hello, My problem is the Queue Growth monitoring ('Tools: Monitoring and Status' Exchange 2003 ESM) seems to be not working properly. I currently have it setup for Warning state: 30mins Critical State: 60mins. I will get an email alert stating critical Queue Growth, so I go check it, and I have 1 whole message waiting in SMTP Queue. When I try to edit the Queue Growth Monitor, it has a box at the bottom that shows 'Current Queue Growth (minutes):80' (80 is just an example, but it always seems to be a high number) even though I will only have like 1 or 2 NDR's awaiting in the SMTP Queue waiting to be sent out. I thought this monitor/alert was for continuous growth of the Queue, not just if you have only 1 email awaiting delivery for over 60 mins? Anyone else having this problem or have a solution to this? Environment: Single Exchange 2003 SP1 on Windows 2003. Thanks! Paul
