Exchange Server 2013 Email Flow Latency Script for multiple Servers

This script help for finding email flow latency between the servers. This will be most useful when you have the exchange servers across the site and perform the mail flow routing.

It works on getting the local server name as source server name and queries each target mailbox servers which is denoted in the array.

$filePath = "C:\temp\Raji\output.txt"

$array = @("MBX1.mail.com","MBX2.mail.com ","MBX3.mail.com ","MBX4.ad.aricent.co.mail.com")

$SourceServer = $env:COMPUTERNAME

ForEach ($TargetServer in $array)

{

Write-host Testing Mailflow from $SourceServer to $TargetServer -foregroundcolor cyan

Add-Content $filePath "Testing Mailflow from $SourceServer to $TargetServer"

$Output = Test-Mailflow -SourceMailboxServer $SourceServer -TargetMailboxServer $TargetServer | FT -Autosize

Write-Output $Output

$Output | Out-File -filePath $filePath -append -encoding ASCII

}

Exchange Server SP1 Upgradation – Things to be considered

Don’t execute the setpup.exe /prepareschema /iacceptexchangeserverlicenseterms of Exchange Server 2013 SP1 in the Windows PowerShell. Instead open the command prompt and execute it.

Reason: when you execute in windows PowerShell it will load the CU3 setup.exe but when you execute in Command prompt it loads SP1. Find the screenshot as follow.

Setup.exe in Command Prompt: Check the Banner ((It shows SP1)

Setup.exe in Windows Powershell: Check the Banner :) (It shows CU3)

Always use Run-As Administrator on the setup.exe when you try to install them in the GUI mode or else you will overcome some error message on access privilege on running the Exchange 2013 Setup
