Exporting the Suggested Contacts, OWA Auto-complete Cache and Recipient Cache in Exchange 2013 with EWS and PowerShell

The following script creates a CSV export of Automatically generated contacts that have been saved in any of the 3 following auto contact locations

Suggested Contacts Folder which is Outlook feature that automatically creates a Contact for each address you send an email to -

OWA Autocomplete Cache - This is OWA version of the NickName cache, its stored in a UserConfiguration object in the Root of the Mailbox. The Addresses are stored inside an XML Streaming Property.

Recipeints Cache Folder - This is a new Exchange 2013 folder which is a hidden sub folder of the Contacts folder with a mailbox and it's purpose isn't really documented at the moment, but contains like the AutoComplete cache,  Addresses for Sent Emails.

So this script just create a CSV file with the Source, DisplayName and Email-address of any entries from these 3 locations.

I've put a download of this script here

The code looks like

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
