The overloaded state is based on a series of resource utilization metrics: Free disk space on the drive(s) that store the message queue database and logs Uncommitted queue http://exchangeserverpro.com/exchange-transport-server-back-pressure/ database transactions in memory Memory utilization by the EdgeTransport.exe process (the Microsoft Exchange Transport service) Overall memory utilization for the server Each of those metrics is measured individually, and as such each is individually capable of causing the server to go into a back pressure state. There are two different levels of back pressure. as well as the condition where no over-utilization is occurring, so in total there are three resource utilization conditions that your Edge or Hub Transport servers can be in: Normal - all is well and the server is performing its role as intended (assuming you haven't modified the back pressure settings to mask a genuine problem - more on that later) Medium - a resource is moderately over-utilized and the server begins limiting some connection types. Typically internal email flow remains functional while email from external or non-Exchange sources will be rejected. High - a resource is severely over-utilized. The server ceases to accept any new connections. For disk space metrics the back pressure condition causes messages to be rejected. However for memory utilization metrics, before rejecting connections the server will first take actions to attempt to relieve the conditions. For example, the server will perform garbage collection (reclaiming memory from unused objects) or flush the server's DNS cache. If after a certai

Exchange 2007 - A few issues resolved At LifeChurch.tv, we're in the middle of the migration project from Exchange 2003 to Exchange 2007.  So far, it's been going very well.  Our single Exchange 2003 Enterprise box is held together with duct tape, chicken wire and spit.  Well, not really, but almost.  It's a nice box - a 4 year old Dell 2650 with a few gigs of ram, 100gig of local storage for OS and 700gig of attached storage for the mailstore.  The issue is that the mailstore is over 500gigs and the attached storage array has a failed drive, no support, and throwing errors every few seconds.  It's literally screaming and flashing red warning lights, and needs help.In August/September, shortly after re-joining the team, I got the new Exchange 2007 Enterprise server setup.  I've gone through a few Exchange 2007 transitions already, and they have been fairly smooth, but this one was a different animal.  A more mobile workforce, lots of PDAs, 99% of our users are laptop users with VPN access and remote email access - so a downtime window is non-existent.  Add on top of that our AWESOME Internet Campus which meets several times at all hours of the day/night and you can see that it's not like there is any real time to move things and cause zero disruption.So, little by little, we've been scheduling and moving mailboxes.  It's been slow because of the old storage issues, backup windows, nonstop disk access by those "working", etc.  We're almost there.  If all goes according to plan, our last Central group (Finance) and our last Campuses (Tulsa and South Tulsa) will make the switch.I wanted to document our setup, and add a few little "gotchas" that we ran into in hope that it might help someone else out there.  I won't give exhaustive how to setup Exchange 2007, but these are specific issues that plagued us.First of all, we have virtualized Exchange 2007.  I've added Exchange as a Virtual Machine in our VMWare ESX 3.5 Cluster.  I gave it the following attributes: 2 vCPUs (2.33Ghz cores) 16gig vRAM (32gig physical on each of 3 - N+1 - ESX hosts) 30gig C: drive (just for OS) - on 15k storage 750gig Data drive (for the datastores - it's 15k rpm virtualized storage on our EMC SAN) 40gig P: drive for Pagefile - again, virtualized I set the pa
