Generating Test Email Data for Exchange Labs with PowerShell

I case you have problems getting this to work due to SSL errors, a bypass is installing the default machine certificate in Trusted Root Authorities. You might be in this scenario if you got a default setup demo enviroment.

For webcrawlers..The error experienced was:
ForEach-Object : Exception calling “Send” with “0″ argument(s): “Request failed. The underlying connection was closed:
Could not establish trust relationship for the SSL/TLS secure channel.”

OK, so I think I got the AutoDiscover errors fixed (at least the error message has changed ). Now i am getting the following error:

[PS] C:\Windows\system32>Get-Mailbox -Identity t001 | Send-LabMailMessage -count -Version Exchange2007_SP1

I thought I read somewhere on this site that you wouldn’t have to log into each mailbox when using the script? I’m getting the ‘WARNING: The user hasn’t logged on to the mailbox’ warning when running a Get-Mailbox | Get-MailboxStatistic command from like half of the users I created with the plug in. I created 5 users in one OU and 5 more in another OU. The issue happens only with the 5 users in the same OU.

Mike,
Have just purchased your MS Exchange 2010 PowerShell Cookbook. On opening I was quickly drawn to Chapter 13 (lucky or unlucky I don’t know). I’ve created ps1 script straight from your txt as below but am coming a cropper on a Proxy Authentication required blip. Is there a way to supply the required in PowerShell and if so, at what stage should i include it in my PS script. Regards Nick Simmonds

Initially I was thinking this might work but I haven’t had success:
#Creates a proxy object and uses the credential I’m running PS as.
$proxy = new-object System.Net.WebProxy(“http://iproxy:80″)
$proxy.UseDefaultCredentials = $true

Actual console error
Exception calling “SendAndSaveCopy” with “0″ argument(s): “The request failed.
The remote server returned an error: (407) Proxy Authentication Required.”

The PS I've jumbled together to send an email on behalf of testuser2@len.com
#Imports the EWS managed APi assembly into the Shell – downloaded and installed into C:\EWS
Add-Type -Path C:\EWS\Microsoft.Exchange.WebServices.dll

#Creates an instance of the ExchangeService class
$svc = New-Object Microsoft.Exchange.WebServices.Data.ExchangeService

#Hooks up a certificate validatiaon callback method setting the EWS VDir certificate to good.
$spm = [System.Net.ServicePointManager]
$spm::ServerCertificateValidationCallback = {$true}

#Sets the EWS end-point using AutoDiscover
$svc.AutoDiscoverUrl("impers@len.com")

#Creates an instance of the EmailMessage class
$msg = New-Object -TypeName Microsoft.Exchange.WebServices.Data.EmailMessage -ArgumentList $svc

#Set specific properties on the $msg object
$msg.Subject = "Test E=Mail"
$msg.Body = "This is a test"
$msg.From = "testuser2@len.com"
$msg.ToRecipients.Add("testuser@len.com")
$msg.SendAndSaveCopy()
