Open “Exchange Management Shell”

Shortcut refs to: (C:\WINDOWS\system32\windowspowershell\v1.0\powershell.exe -PSConsoleFile “C:\Program Files\Microsoft\Exchange Server\bin\exshell.psc1” -noexit -command “. ‘C:\Program Files\Microsoft\Exchange Server\bin\Exchange.ps1′”)

If this is not installed, look at the following article for installing Exchange: http://technet.microsoft.com/en-us/library/bb123694(EXCHG.80).aspx

Don’t get the Exchange Management Shell & Windows Powershell mixed up – for Windows Powershell see:

List all Public folder email addresses (output to file) 

I had a request for all the email addresses associated to public mailboxes, as these are not displayed on the client in Outlook.

Get-PublicFolder -Recurse | Get-MailPublicFolder | fl DisplayName,Emailaddresses > c:\publicfolders_list.txt

Method2: Displays a list of Public Folders & Email addresses output to CSV File:

Type the below, replacing ‘public folder name’ with your public folder name/path and you must keep the \ at the front of it and also replace ‘username’ with the username:

Owner can be replaced with the following roles:

  • None
  • Owner
  • PublishingEditor
  • Editor
  • PublishingAuthor
  • Author
  • Non-Editing Author
