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.

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 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 '

Export calendar Items to a CSV file using EWS and Powershell

Somebody asked about this last week and while I have a lot of EWS scripts that do access the Calendar I didn't have a simple example that just exported a list of the Calendar events with relevant information to a CSV file so here it is. I've talked on this one before in this howto  but when you query the calendar folder using EWS you need to use a CalendarView which will expand any recurring appointments in a calendar. There are some limits when you use a calendarview in that you can only return a maximum of 2 years of appointments at a time and paging will limit the max number of items to 1000 per call. So if you have a calendar with a very large number of appointments you need to break your query into small date time blocks. In this example script I'm just grabbing the next 7 days of appointments if you want to query a longer period you need to adjust the following lines (keeping in mind what I just mentioned) #Define Date to Query $StartDate = (Get-Date) $EndDate

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 .  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
