Using the new EWS password expiration operation in Exchange 2010 SP2 in Powershell

If it hadn't escaped your notice Exchange 2010 SP2 was released this week although from an EWS perspective there isn't that much to shout about one of the interesting new operations is the GetPasswordExpiration operation. This allows you to get the DateTime when the password for an account will expire. Currently version 1.1 of the Managed API doesn't support this operation but from the information that has been released the next version should. In the meantime you can take advantage of this new operation using some raw SOAP.

The following is a quick sample script that makes a GetPasswordExpiration request there is some SSL ignore code so it should run okay in a test environment without a valid SSL cert. To use this script you need to configure the following variables.

$MailboxName = "user@domain.com" 
      
$cred = New-Object System.Net.NetworkCredential("user@domamin.com","password")

If you don't have autodiscover configured if your trying in a dev/test enviroment you can also hardcode the CASURL in

$mbMailboxFolderURI = New-Object System.Uri("https://192.168.42.132/ews/exchange.asmx") 

I've put a download of this script here the script itself looks like


  1. $MailboxName = "user@domain.com"    
  2.          
  3. $cred = New-Object System.Net.NetworkCredential("user@domamin.com","password")

The MailboxConcurrency limit and using Batching in the Microsoft Graph API

If your getting an error such as Application is over its MailboxConcurrency limit while using the Microsoft Graph API this post may help you understand why. Background   The Mailbox  concurrency limit when your using the Graph API is 4 as per https://docs.microsoft.com/en-us/graph/throttling#outlook-service-limits . This is evaluated for each app ID and mailbox combination so this means you can have different apps running under the same credentials and the poor behavior of one won't cause the other to be throttled. If you compared that to EWS you could have up to 27 concurrent connections but they are shared across all apps on a first come first served basis. Batching Batching in the Graph API is a way of combining multiple requests into a single HTTP request. Batching in the Exchange Mail API's EWS and MAPI has been around for a long time and its common, for email Apps to process large numbers of smaller items for a variety of reasons.  Batching in the Gr...

Exporting and Uploading Mailbox Items using Exchange Web Services using the new ExportItems and UploadItems operations in Exchange 2010 SP1

Two new EWS Operations ExportItems and UploadItems where introduced in Exchange 2010 SP1 that allowed you to do a number of useful things that where previously not possible using Exchange Web Services. Any object that Exchange stores is basically a collection of properties for example a message object is a collection of Message properties, Recipient properties and Attachment properties with a few meta properties that describe the underlying storage thrown in. Normally when using EWS you can access these properties in a number of a ways eg one example is using the strongly type objects such as emailmessage that presents the underlying properties in an intuitive way that's easy to use. Another way is using Extended Properties to access the underlying properties directly. However previously in EWS there was no method to access every property of a message hence there is no way to export or import an item and maintain full fidelity of every property on that item (you could export the...

EWS-FAI Module for browsing and updating Exchange Folder Associated Items from PowerShell

Folder Associated Items are hidden Items in Exchange Mailbox folders that are commonly used to hold configuration settings for various Mailbox Clients and services that use Mailboxes. Some common examples of FAI's are Categories,OWA Signatures and WorkHours there is some more detailed documentation in the https://msdn.microsoft.com/en-us/library/cc463899(v=exchg.80).aspx protocol document. In EWS these configuration items can be accessed via the UserConfiguration operation https://msdn.microsoft.com/en-us/library/office/dd899439(v=exchg.150).aspx which will give you access to either the RoamingDictionary, XMLStream or BinaryStream data properties that holds the configuration depending on what type of FAI data is being stored. I've written a number of scripts over the years that target particular FAI's (eg this one that reads the workhours  http://gsexdev.blogspot.com.au/2015/11/finding-timezone-being-used-in-mailbox.html is a good example ) but I didn't have a gene...
