Enumerating and Reporting on all Search Folders in a Mailbox or Archive with EWS and Powershell

Search Folders are a feature of Exchange that allows you to have a static search based on a particular criteria  across one or more folders in a Mailbox. They can serve a number of different functions within a Mailbox and are often used to provide some of the backend functionality of new features.

None of the Exchange Management Shell cmdlets gives you  a good view of the SearchFolders in a Mailbox so EWS can be particular useful for this.

It will produce a report such as

I've put a copy of this script up on GitHub here https://github.com/gscales/Powershell-Scripts/blob/master/SearchFoldersEnums.ps1

To Run the script use

Get-SearchFolders -MailboxName Mailbox@domain.com

to Get Searchfolder from an Archive

Get-SearchFolders -MailboxName Mailbox@domain.com -Archive

to use EWS Impersonation

Get-SearchFolders -MailboxName Mailbox@domain.com -useImpersonation
