PowerShell Out-File

I am fairly new to PowerShell scripting. I have created a very simple script that pipes a couple of commands and displays on screen with different colors for different results. I want to take the on screen data and put all of it into a txt file, which eventually I'll use for Zabbix alerts.

The script executes and creates the txt file, yet the txt file is empty. Any assistance would be great!

Code:

Get-MailboxServer | Get-mailboxDatabaseCopyStatus | ForEach {

  If ($_.Status.ToString() -notmatch "Mounted" -or $_.ContentIndexState.ToString() -notmatch "Healthy")

  {

        Write-Host "$($_.Name) - $($_.Status) - $($_.ContentIndexState) - OK" -ForegroundColor Green

  }

  Else

  {

        Write-Host "$($_.Name) - $($_.Status) - $($_.ContentIndexState) - FAILED" -ForegroundColor Red

  }     

} | set-content | out-file c:\scripts\exchangedb.log
