IMF message tracking ID's and Spam Report script

If you have Message Tracking Logging enabled on your server then Exchange records details about the message transfer process into the message tracking logs which can then be searched via Exchange System Manager - Message Tracking Center. A full list of Tacking ID and descriptions for Exchange 2003 can be found in the Exchange FAQ . With the release of the IMF there are now some new Tracking ID's that get logged when the IMF takes action on a message at the gateway level. The ID's look like this

1039 SMTP:Message Deleted by Intelligent Message Filtering
1040 SMTP:Message Rejected by Intelligent Message Filtering
1041 SMTP:Messgae Archived by Intelligent Message Filtering

Depending on how you have your Gateway actions set you will get 1 or 2 of theses events logged when a gateway action is performed , Eg if you have your gateway action set to archive you get a 1041 logged and then a 1039 logged.
Apart from System Manager the Message tracking logs can be accessed via WMI using the Exchange_MessageTrackingEntry Class which is part of the ROOT\MicrosoftExchangeV2 Namespace.

As part of my daily Sys-Admin duties I wanted to be able to check what emails the IMF took action on over the past day, so what I came up with is a script that uses a WMI WQL query of all the 1039 events for the past day, puts the results in a HTML table and then emails me. The script I used is below - There are some time conversion routines to convert UTC times to local and also construct the time variable format required for WQL. The only other thing of note is that I have subject logging enable on my server which the script expects. To use it I just created a scheduled task that runs the script once a day in the morning.

Its had about a day of testing (the joys of blogging) and worked okay last night Enjoy.

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...

Sending a Message in Exchange Online via REST from an Arduino MKR1000

This is part 2 of my MKR1000 article, in this previous post  I looked at sending a Message via EWS using Basic Authentication.  In this Post I'll look at using the new Outlook REST API  which requires using OAuth authentication to get an Access Token. The prerequisites for this sketch are the same as in the other post with the addition of the ArduinoJson library  https://github.com/bblanchon/ArduinoJson  which is used to parse the Authentication Results to extract the Access Token. Also the SSL certificates for the login.windows.net  and outlook.office365.com need to be uploaded to the devices using the wifi101 Firmware updater. To use Token Authentication you need to register an Application in Azure https://msdn.microsoft.com/en-us/office/office365/howto/add-common-consent-manually  with the Mail.Send permission. The application should be a Native Client app that use the Out of Band Callback urn:ietf:wg:oauth:2.0:oob. You ...

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...
