Mailbox retention tag application and management are one of the more complex administrative tasks on Exchange from 2010 and one task scripting can be a great help with. With EWS there are two ways you can deal with retrieving the Retention Tags that have been applied to a Folder or Item. In 2013 and 2016,  EWS returns the retention tags applied to a folder or Item as a Strongly typed property which makes things easier to deal with. In Exchange 2010 you need to access the underlying extended properties for Retention tags (this will also work on 2013 and 2016 because the extended properties are the same). I've posted up a script module on GitHub here https://github.com/gscales/Powershell-Scripts/blob/master/ReportTagged.ps1  that can do this using the Extended properties so it will work on Exchange 2010 and up. Report-TaggedFolders  - Creates a Report of the FolderTag applied to each of the Folders in a Mailbox (if they are tagged). To get all the availbi...

This is a rollup post for a couple of scripts I've posted in the past for creating folders using EWS in an Exchange OnPremise or Exchange online Cloud mailbox. It can do the following Create a Folder in the Root of the Mailbox Create-Folder -Mailboxname mailbox@domain.com -NewFolderName test Create a Folder as a SubFolder of the Inbox Create-Folder -Mailboxname mailbox@domain.com -NewFolderName test -ParentFolder '\Inbox' Create a Folder as a SubFolder of the Inbox using EWS Impersonation Create-Folder -Mailboxname mailbox@domain.com -NewFolderName test -ParentFolder '\Inbox' -useImpersonation Create a new Contacts Folder as a SubFolder of the Mailboxes Contacts Folder Create-Folder -Mailboxname mailbox@domain.com -NewFolderName test -ParentFolder '\Contacts' -FolderClass IPF.Contact Create a new Calendar Folder as a SubFolder of the Mailboxes Calendar Folder Create-Folder -Mailboxname mailbox@domain.com -NewFolderName test -Parent...

Somebody asked a question the other week about getting all the Folder Sizes via EWS which you can do easily using the PR_MESSAGE_SIZE_EXTENDED property and FindFolders operation (you can also get the folder size's using the Exchange Management Shell via Get-MailboxFolderStatistics cmdlet). But there is some other interesting stuff you can get via EWS that you can't from the EMS cmdlet such as the Default FolderClass (eg the PR_CONTAINER_CLASS_W http://msdn.microsoft.com/en-us/library/office/cc839839(v=office.15).aspx ) which will tell you what items are being stored in that particular Folder (although as documented it's not a mandatory property although its absence in the past has caused problem in OWA etc). Another property that looks interesting but doesn't seem to be well documented is the PR_ATTACH_ON_NORMAL_MSG_COUNT which appears to the be the total number of attachments on messages in that folder including seemly inline attachment (Note I can't confirm this a...

I've had a few questions about this in the past week so I thought I would put together a quick sample to show how you can create a new Folder is EWS and set the FolderClass so it appears as a Calendar, Contacts, Tasks, Notes or whatever other folder you want. This is a function so you can just cut and paste it into your own script to use. The full script looks like the following which has samples of using the function at the bottom. ## Get the Mailbox to Access from the 1st commandline argument       $MailboxName  =  $args [0]      ## Load Managed API dll      Add-Type -Path  "C:\Program Files\Microsoft\Exchange\Web Services\1.2\Microsoft.Exchange.WebServices.dll"           ## Set Exchange Version      $ExchangeVersion  = [Micro...
