PowerShell to check file exist in the destination folder before exporting the Exchange email as .PST?

Hi People,

I need some assistance in fixing the below PowerShell script that can do the export First.LastName@domain.com.PST from the .CSV input file:

Code: Select all

Johny Hargreaves
Linda Marino
Henry Hosain
Vicki Cunard
Amalia Stokes
...
Check if the exported First.LastName@domain.com.PST is already existing on the destination fileserver \\PRODFS01-VM\PST\
if it exists then skip it and append the list First.LastName@domain.com.PST to a text file.
If not exist, then do the Export to PST as \\PRODFS01-VM\PST\First.LastName@domain.com.PST

Code: Select all

$Server = 'PRODFS01-VM'
$ServerBackupUNCPath = "\\$Server\PST\"
$InputCSVPath = 'C:\LOGS\Users.csv'
$ExportCSVPath = 'C:\LOGS\Output.csv'
$ExportExistsCSVPath = 'C:\LOGS\Exist.csv'

Import-PSSession ($Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri http://PRDEXC08-VM/Powershell/ -Authentication Kerberos)

Get-Content -Path $InputCSVPath |
  Get-MailBox | 
  % {
    Write-Host "Processing .... $($_.Name) ..." -ForegroundColor Green
	
	# Check if the file already exist or not
	$FileResult = Get-WmiObject CIM_DataFile -ComputerName $Server -filter "path='$ServerBackupUNCPath'" | ? {$_.name -match "$($_.Alias).PST" }
	
	if ( $FileResult -eq $null ) {
		#If there is no exported .PST file on the destination folder, then begin the export mailbox command and log if there any error to the AliasName.LOG file:
	    New-MailboxExportRequest -Mailbox $_ -FilePath "$ServerBackupUNCPath$($_.Alias).PST" -baditemlimit 50 -acceptlargedataloss 
	    # wait until error or processed:
	    while ( ($req = Get-MailboxExportRequest $_) | ? { $_.Status -match 'Queued|InProgress' } )
	    { Start-Sleep 180 } 
	    $req | Get-MailboxExportRequestStatistics -IncludeReport | Select -Expand Report | Out-File "C:\LOGS\$($_.Alias).log"
	} else {
		Write-Output "The user $($_.Alias).PST file is already existing"
		#Append the list of already existing list of users C:\LOGS\Exist.csv
		($_.Alias) | Out-File -FilePath $ExportExistsCSVPath -Append
	}
	
	# I assume, whatever line I put here will be executed regardless of any of the condition above is met or not
	Remove-Mailbox -Identity $_ -Confirm $false -WhatIf
  }
The line to do the comparison and appending the name of the already existing files is not working, hence I need some help to fix it.

Any help would be greatly appreciated very muchly.

Thanks,

Thanks in advance,

Unfortunately your CSV file is not a CSV file and it does not contain names that can be piped to Get-Mailbox. You can only pipe identities to the CmdLet.

Hi Mr. Vierra,

Actually I have converted those names with the other lines of code to WindowsEmailAddress format, so the input is now First.Last@domain.com

Your help to assist me in this scripting would be muchly appreciated.

Where did you do this? The code doesn't do anything like that.

Using WMI to test for a file will never work. It is not like a directory listing. It cannot get UNC paths.

Use "Test-Path" to test for the file.

This is the code that converts the list of First Last name into the email address into .CSV:

Code: Select all

$Users = Get-Content -Path $InputCSVPath
&{
	foreach ($User in $Users) {
		Write-Host "Processing.... $User"
		Get-Mailbox $User.ToString() | Select WindowsEmailAddress 
	} 
}| Export-Csv -Path $ExportCSVPath -NoTypeInformation

Same issue. What is this: "Get-Content -Path $InputCSVPath"

You cannot .load a CSV suing Get-Content. A Csv has headers and columns. Get-Content will not convert it into anything.

What is this supposed to do?

Code: Select all

&{
	foreach ($User in $Users) {
		Write-Host "Processing.... $User"
		Get-Mailbox $User.ToString() | Select WindowsEmailAddress 
	} 
}[/code}

Is this what you are trying to do?

[code]
Get-Content -Path <text file path> |
    Get-Mailbox $_ | 
    Select WindowsEmailAddress |
    Export-Csv -Path $ExportCSVPath -NoTypeInformation
The text file must have an "identity" for each mailbox.

Hi Mr. Vierra,

This is the updated code that I have adapted based on your suggestion.

Code: Select all

$Server = 'PRODFS01-VM'
$ServerBackupUNCPath = "\\$Server\PST"
$InputCSVPath = 'C:\LOGS\Input.csv'
$ExportCSVPath = 'C:\LOGS\Output.csv'
$ExportExistsCSVPath = 'C:\LOGS\EmailExist.csv'

Import-PSSession ($Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri http://PRDEXC03-VM/Powershell/ -Authentication Kerberos)

$Users = Get-Content -Path $InputCSVPath
&{
	foreach ($User in $Users) {
		Write-Host "Processing.... $User"
		Get-Mailbox $User.ToString() | Select WindowsEmailAddress 
	} 
} | Export-Csv -Path $ExportCSVPath -NoTypeInformation

Import-Csv -Path $ExportCSVPath |
  Get-MailBox | 
  % {
    Write-Host "Processing .... $($_.Name) ..." -ForegroundColor Green
	
	# Check if the file already exist or not
	$FileResult = Test-Path -Path "$ServerBackupUNCPath\$($_.WindowsEmailAddress).PST" -PathType Leaf
	
	if ( $FileResult -ne $True ) {
		#If there is no exported .PST file on the destination folder, then begin the export mailbox command and log if there any error to the AliasName.LOG file:
	    New-MailboxExportRequest -Mailbox $_ -FilePath "$ServerBackupUNCPath\$($_.WindowsEmailAddress).PST" -BadItemLimit 50 -AcceptLargeDataLoss -WhatIf
	    # wait until error or processed:
	    while ( ($req = Get-MailboxExportRequest $_) | ? { $_.Status -match 'Queued|InProgress' } )
	    { Start-Sleep 180 } 
	    $req | Get-MailboxExportRequestStatistics -IncludeReport | Select -Expand Report | Out-File "C:\LOGS\$($_.WindowsEmailAddress).log"
	} else {
		Write-Output "The user $($_.WindowsEmailAddress).PST file is already existing"
		#Append the list of already existing list of users C:\LOGS\Exist.csv
		($_.Alias) | Out-File -FilePath $ExportExistsCSVPath -Append
	}
	
	# I assume, whatever line I put here will be executed regardless of any of the condition above is met or not
	Write-Host "Removing Mailbox $($_.WindowsEmailAddress)" -ForegroundColor Red
	Remove-Mailbox -Identity $_ -Confirm $false -WhatIf
	
  }
The ExportedCSV is nicely formatted as the email address like the below:
The only error is:

Code: Select all

Where did you do this? The code doesn't do anything like that.
I have updated and minimize the error to just around the Import-Csv -Path $ExportCSVPath | Get-MailBox $_ section.

This is the updated code:

Code: Select all

$Server = 'PRDFILESVR01-VM'
$ServerBackupUNCPath = "\\$Server\PST"
$InputCSVPath = 'C:\LOGS\Input.csv'
$ExportCSVPath = 'C:\LOGS\Output.csv'
$ExportExistsCSVPath = 'C:\LOGS\Exist.csv'

#Import-PSSession ($Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri http://PRDEXC03-VM/Powershell/ -Authentication Kerberos)

$Users = Get-Content -Path $InputCSVPath
&{
	foreach ($User in $Users) {
		Write-Host "Processing.... $User"
		Get-Mailbox $User.ToString() | Select PrimarySmtpAddress 
	} 
} | Export-Csv -Path $ExportCSVPath -NoTypeInformation

Import-Csv -Path $ExportCSVPath |
  Get-MailBox $_ | 
  % {
    Write-Host "Processing .... $($_.Name) ..." -ForegroundColor Green
	
	# Check if the file already exist or not
	$FileResult = Test-Path -Path "$ServerBackupUNCPath\$($_.PrimarySmtpAddress).PST" -PathType Leaf
	
	if ( $FileResult -ne $True ) {
		#If there is no exported .PST file on the destination folder, then begin the export mailbox command and log if there any error to the AliasName.LOG file:
	    New-MailboxExportRequest -Mailbox $_ -FilePath "$ServerBackupUNCPath\$($_.PrimarySmtpAddress).PST" -BadItemLimit 50 -AcceptLargeDataLoss -WhatIf
	} else {
		Write-Output "The user $($_.PrimarySmtpAddress).PST file is already existing"
		#Append the list of already existing list of users C:\LOGS\Exist.csv
		Get-MailboxExportRequestStatistics -IncludeReport | Select -Expand Report | Out-File "C:\LOGS\$($_.PrimarySmtpAddress).log"
	}
	
	# I assume, whetever line I put here will be executed regardless of any of the condition above is met or not
	#Remove-Mailbox -Identity $_.PrimarySmtpAddress -Confirm $false -WhatIf
	Write-Host "Removing Mailbox $($_.PrimarySmtpAddress)" -ForegroundColor Red
  }
Here's the error message:
The input object cannot be bound to any parameters for the command either because the command does not take pipeline input or the input and its properties do not match any of the parameters that take pipeline input.

Its a CSV. You have to reference it correctly. We've done this many times before.

Import-Csv -Path $ExportCSVPath |
Get-MailBox $_.PrimarySmtpAddress |
