Public Folder Cheat Sheet

Some PowerShell stuff for working with Exchange Public Folders. I will add content as needed. This page is my personal cheat sheet. Maybe it can help you, too.

General stuff

# Export public folder statistics
Get-PublicFolderStatistics -ResultSize Unlimited | Select-Object Name, FolderPath, ItemCount, TotalItemSize | Export-csv ".\PFStatistics-$(Get-Date -Format 'yyyMMdd-hhmm').csv" -Encoding utf8 -NoTypeInformation

# Cleanup alias (mailnickname) of mail enabled public folders
# Required for legacy to modern public folder migration (On-Premises/Online)

$publicFolders = Get-PublicFolder -Identity "\" -Recurse -ResultSize Unlimited | Get-MailPublicFolder | Where {$_.Alias -like "* *"}
$publicFolders | ForEach-Object { Set-MailPublicFolder $_.identity -Alias:($_.Alias -Replace " ","") }

Scripts

• Get-NewPublicFolders.ps1
  This script exports the folder created during the last X days.
  The information helps you to understand how your users (still) utilize public folders and to prepare a migration or even the full decommissioning of public folders.
