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 = "" 
$cred = New-Object System.Net.NetworkCredential("","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("") 

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

  1. $MailboxName = ""    
  3. $cred = New-Object System.Net.NetworkCredential("","password")     
  5. $dllpath = "C:\Program Files\Microsoft\Exchange\Web Services\1.1\Microsoft.Exchange.WebServices.dll"

Testing and Sending email via SMTP using Opportunistic TLS and oAuth in Office365 with PowerShell

As well as EWS and Remote PowerShell (RPS) other mail protocols POP3, IMAP and SMTP have had OAuth authentication enabled in Exchange Online (Official announcement here ). A while ago I created  this script that used Opportunistic TLS to perform a Telnet style test against a SMTP server using SMTP AUTH. Now that oAuth authentication has been enabled in office365 I've updated this script to be able to use oAuth instead of SMTP Auth to test against Office365. I've also included a function to actually send a Message. Token Acquisition  To Send a Mail using oAuth you first need to get an Access token from Azure AD there are plenty of ways of doing this in PowerShell. You could use a library like MSAL or ADAL (just google your favoured method) or use a library less approach which I've included with this script . Whatever way you do this you need to make sure that your application registration

How to access and restore deleted Items (Recoverable Items) in the Exchange Online Mailbox dumpster with the Microsoft Graph API and PowerShell

As the information on how to do this would cover multiple posts, I've bound this into a series of mini post docs in my GitHub Repo to try and make this subject a little easier to understand and hopefully navigate for most people.   The Binder index is   The topics covered are How you can access the Recoverable Items Folders (and get the size of these folders)  How you can access and search for items in the Deletions and Purges Folders and also how you can Export an item to an Eml from that folder How you can Restore a Deleted Item back to the folder it was deleted from (using the Last Active Parent FolderId) and the sample script is located

Using the MSAL (Microsoft Authentication Library) in EWS with Office365

Last July Microsoft announced here they would be disabling basic authentication in EWS on October 13 2020 which is now a little over a year away. Given the amount of time that has passed since the announcement any line of business applications or third party applications that you use that had been using Basic authentication should have been modified or upgraded to support using oAuth. If this isn't the case the time to take action is now. When you need to migrate a .NET app or script you have using EWS and basic Authentication you have two Authentication libraries you can choose from ADAL - Azure AD Authentication Library (uses the v1 Azure AD Endpoint) MSAL - Microsoft Authentication Library (uses the v2 Microsoft Identity Platform Endpoint) the most common library you will come across in use is the ADAL libraries because its been around the longest, has good support across a number of languages and allows complex authentications scenarios with support for SAML etc. The
