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")

Export calendar Items to a CSV file using Microsoft Graph and Powershell

For the last couple of years the most constantly popular post by number of views on this blog has been  Export calendar Items to a CSV file using EWS and Powershell closely followed by the contact exports scripts. It goes to show this is just a perennial issue that exists around Mail servers, I think the first VBS script I wrote to do this type of thing was late 90's against Exchange 5.5 using cdo 1.2. Now it's 2020 and if your running Office365 you should really be using the Microsoft Graph API to do this. So what I've done is create a PowerShell Module (and I made it a one file script for those that are more comfortable with that format) that's a port of the EWS script above that is so popular. This script uses the ADAL library for Modern Authentication (which if you grab the library from the PowerShell gallery will come down with the module). Most EWS properties map one to one with the Graph and the Graph actually provides better information on recurrences then...

Downloading a shared file from Onedrive for business using Powershell

I thought I'd quickly share this script I came up with to download a file that was shared using One Drive for Business (which is SharePoint under the covers) with Powershell. The following script takes a OneDrive for business URL which would look like https://mydom-my.sharepoint.com/personal/gscales_domain_com/Documents/Email%20attachments/filename.txt This script is pretty simple it uses the SharePoint CSOM (Client side object Model) which it loads in the first line. It uses the URI object to separate the host and relative URL which the CSOM requires and also the SharePointOnlineCredentials object to handle the Office365 SharePoint online authentication. The following script is a function that take the OneDrive URL, Credentials for Office365 and path you want to download the file to and downloads the file. eg to run the script you would use something like ./spdownload.ps1 ' https://mydom-my.sharepoint.com/personal/gscales_domain_com/Documents/Email%20attachments/filen...

Sending a MimeMessage via the Microsoft Graph using the Graph SDK, MimeKit and MSAL

One of the new features added to the Microsoft Graph recently was the ability to create and send Mime Messages (you have been able to get Message as Mime for a while). This is useful in a number of different scenarios especially when trying to create a Message with inline Images which has historically been hard to do with both the Graph and EWS (if you don't use MIME). It also opens up using SMIME for encryption and a more easy migration path for sending using SMTP in some apps. MimeKit is a great open source library for parsing and creating MIME messages so it offers a really easy solution for tackling this issue. The current documentation on Send message via MIME lacks any real sample so I've put together a quick console app that use MSAL, MIME kit and the Graph SDK to send a Message via MIME. As the current Graph SDK also doesn't support sending via MIME either there is a workaround for this in the future my guess is this will be supported.
