Pull Subscription Mailbox Item move tracking script MEC sample 2

This is the second of the Powershell script samples from my MEC talk last week. The idea behind this script is to track the movement of Items in a Mailbox between folders using Pull Notifications in EWS, you can read more about how Pull notifications work here .  This script takes advantage of the fact that when you enable Single Item Recovery any deletes you make in a Mailbox (hard or soft) the Items aren't deleted rather moved to the Dumpster v2 RecoverableItems folders. So if you track all the move notification events you can track both the movement of Messages by rules, users or deletes. eg the results look like



I've created two different versions of this script, the first version subscribes to all folders in a Mailbox and runs continuously against the Mailbox and does a GetEvents request every minute to retrieve the latest events from all folders in a Mailbox and then logs that to file.

The second version just subscribes to the Inbox folder and saves the subscription information out to file when you run it the first time. Then the next time you run the script it will use the saved SubscriptionId and Watermark value to get all the events since the script was last run. Pull Subscriptions have a timeout of 1440 minutes (which is 1 day) so if you are going to run this version you need to run it with a maximum gap of 1 day. The idea of this second version was just to track inbox fan-out of messages rather then subscribing to all folders like the first version.

Both of these scripts use EWS Impersonation which must be configured for the account your going to run the script as. When you run the script you need to pass in the Mailbox to run against and the timeout value in minutes for subscription which needs to between 1 and 1440 eg

./pullSubTrackWm.ps1 jcool@msgdevelop.onmicrosoft.com 1440

I've put a download of both scripts here the code itself 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  https://docs.microsoft.com/en-us/azure/active-directory/develop/quickstart-register-

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 Graph is limited to a m

How to test SMTP using Opportunistic TLS with Powershell and grab the public certificate a SMTP server is using

Most email services these day employ Opportunistic TLS when trying to send Messages which means that wherever possible the Messages will be encrypted rather then the plain text legacy of SMTP.  This method was defined in RFC 3207 "SMTP Service Extension for Secure SMTP over Transport Layer Security" and  there's a quite a good explanation of Opportunistic TLS on Wikipedia  https://en.wikipedia.org/wiki/Opportunistic_TLS .  This is used for both Server to Server (eg MTA to MTA) and Client to server (Eg a Message client like Outlook which acts as a MSA) the later being generally Authenticated. Basically it allows you to have a normal plain text SMTP conversation that is then upgraded to TLS using the STARTTLS verb. Not all servers will support this verb so if its not supported then a message is just sent as Plain text. TLS relies on PKI certificates and the administrative issue s that come around certificate management like expired certificates which is why I wrote th
