Detect Backpressure on your Exchange Servers

Scenario:  Customers are complaining about connectivity issues and degraded performance with their mail clients. You suspect its due to backpressure on a server, but you want to dig a little deeper.


1.Check for Windows Event 2002 “The number of outstanding requests for guard TargetBackend has exceeded the max limit 150. Current request will be rejected” by running this PowerShell command:

Get-WinEvent -computername <remote computer> -FilterHashtable @{logname=’application’;id=2002}


2. Check the number of mounted copies of mounted Exchange Databases on each server and manually spread them out:

(get-mailboxdatabasecopystatus -server <remote computer> | Where status -like Mounted).count

3. Check for user counts and compare against each server by running this Powershell Command:

(Get-WmiObject Win32_LoggedOnUser -ComputerName <remote computer>| Select Antecedent -Unique).count
