Powershell - If file not in attachment - powershell

Question

Using the below code how do I put a check in place that if the $FileName doesn't exist in the email then fail.
Ideally I want something like this -
Write-Host "Attachment $FileName does not exist for download."; exit 1
But I'm not sure where to put it in the code.
$EmailwithAttachments = [Microsoft.Exchange.WebServices.Data.EmailMessage]::Bind($service, $Email.Id, $emailProps)
Foreach ($File in $EmailwithAttachments.Attachments) {
If ($File.name -eq $FileName) {
Try {
#Just to be safe, remove any invaild characters from the attachment name
$FileName = $File.name -replace ("[{0}]" -f ([RegEx]::Escape([String][System.IO.Path]::GetInvalidFileNameChars())))
#Current can't handle Emails that are attacments, so we skip them
Write-Host "Attachment $FileName exists for download."
If ($File.contenttype -eq $null) {
Write-Warning "Attachment is an email, skipping"
$EMLAttachment = $TRUE
continue
}
Else {
$EMLAttachment = $FALSE
}
$File.load($SavePath + "\\" + $FileName)
If (($FileName -like "*.zip") -and $UnZipFiles) {$ZipFileNames += $SavePath + "\"+ $FileName}
}
Catch {
Send-ErrorReport -Subject "Attachment save path cannot be accessed" -body "Please verify the following path <B>$SavePath</B><BR>Full Error:<BR> $_" -HaltScript
}
}
}
If ($UnZipFiles) {
Try {
$shell = new-object -com shell.application
$Location = $shell.namespace($SavePath)
foreach ($ZipFile in $ZipFileNames) {
$ZipFolder = $shell.namespace($ZipFile)
$Location.Copyhere($ZipFolder.items())
Remove-item $ZipFile
}
}
Catch {
Send-ErrorReport -Subject "Attachment save path cannot be accessed" -body "Please verify the following path <B>$SavePath</B><BR>Full Error:<BR> $_" -HaltScript
}
}
}
}
$strFileName=($SavePath + "\\" + $FileName)
If (Test-Path $strFileName){
If ((Get-Content $strFileName) -eq "") {
"File Exists and is empty"; exit 1
}Else{
"File Exists and is stable."
}
}Else{
"File Does Not Exist"; exit 1
}

Answer 1

your $filename variable is empty, it should be declared before you can put it in your If statement, declare it before like this:
$EmailwithAttachments = [Microsoft.Exchange.WebServices.Data.EmailMessage]::Bind($service, $Email.Id, $emailProps)
$Filename = MyFileName
Foreach ($File in $EmailwithAttachments.Attachments) {
If ($File.name -eq $FileName)
