Exchange 2007 Content Agent Log Message Tracker Gui

One of the cool features from a logging perspective on Exchange 2007 is the ability to log the SCL of every message when you have the Content Filtering Agent enabled (and also logging enabled). There is a Exchange Management Shell powershell cmdlet for reading these logs called get-agentlog which gives a good cmdline experience but as these logs are something you might want to check on a regular basis and the information contained in them is a little unwieldy to display in a cmdline environment I decided to put together a little GUI to make my life a little easier. I based the GUI on my Exchange 2000/3 WMI message tracker and I was able to carry over a lot of the cool little aggregation functions of this utility using most of the same code with a few tweaks here and there.
What this script does is creates a Winform and adds a whole bunch of controls to that winform such as datapickers, textboxes, checkboxes,labels and buttons. Its then wires ups some functions to the button clicks so that when you click the search button in will run the get-agentlog cmdlet with parameters for the daterange you specified in the GUI. To make sure you only get the events in the log that relate to the content filter it use a filter $_.agent -eq "Content Filter Agent”
The data returned by get-agent log is then added to a ADO.NET data table which is then data bound to a datagridview to display back in the form. Clicking the export button will fire a save-file dialogue box and some code will then export the table results to a csv file.
There are textboxes to allows you to search based on the from and/or To address.
There is a drop down list to allow you to select a SCL level to look at so you can choose to filter by only messages that have been assigned a specific SCL value.
The Extra sections has the aggregate options currently it has four aggregate option is can aggregate
By SCL this shows you by SCL Value how many messages where received between the dates specified
By Receiver will show you grouped by receiver how many messages have been received for each SCL value
By Sender will show you grouped by Sender(P1) how many messages have been received for each SCL value
By Date will show you by Date how many messages have been received for each SCL value.
Currently the script is only designed to be run locally on the Exchange box where the agent logs files are located. The Get-agentlog cmdlet doesn’t have a server parameter although it does have a log file location parameter so this maybe an option if you did want to run this script from a machine other then the Local Exchange server. To run the script is basically straight forward when you run it the script will build the winform and should then present this as an active window. Select the date you want to scan and the click the search button.
This is really only kind of scratching the surface of what you could do with the agent logs im working on a geolcation version so I can show the country origins of SCL values and also a version that will integrated the message tracking logs so I can include subject information in with the SCL. Also there is a lot more then just the content filtering information stored in the agent logs other things such as RBL use and effectiveness can be reported and other Transport agents that log to these files.
I’ve put a download of the code here It’s a bit to large to past verbaitem in the blog the main get-aglog section looks like
$filter = "$_.agent -eq ""Content Filter Agent"""
$dtQueryDT = New-Object System.DateTime $dpTimeFrom.value.year,$dpTimeFrom.value.month,$dpTimeFrom.value.day,$dpTimeFrom2.value.hour,$dpTimeFrom2.value.minute,$dpTimeFrom2.value.second
$dtQueryDTf = New-Object System.DateTime $dpTimeFrom1.value.year,$dpTimeFrom1.value.month,$dpTimeFrom1.value.day,$dpTimeFrom3.value.hour,$dpTimeFrom3.value.minute,$dpTimeFrom3.value.second
if ($extrasettings -eq 0){

$exclude = 0

[String]$sclival = "SCL " + $_.ReasonData
if ($sclhash.ContainsKey($sclival)){
$tsize = [int]$sclhash[$sclival] + 1
$sclhash[$sclival] = $tsize
}
else{
$sclhash.add($sclival,1)
}

}
if ($GroupByReciever.Checked -eq $true){
foreach($recp in $_.Recipients){
$sclagkey = $recp.ToString().replace("|","-") + "|" + $_.ReasonData
AggResults($sclagkey)

$sclagkey = $_.Timestamp.toshortdatestring().replace("|","-") + "|" + $_.ReasonData
AggResults($sclagkey)
}

}

foreach($sclval in $sclhash.keys){
$sclTable.rows.add("",$sclval,$sclhash[$sclval])

$daDatarray = $adr.split("|")

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

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

A walk-though using the Graph API Mailbox reports in Powershell

Quite recently the Reporting side of the Graph API has moved in GA from beta, there are quite a number of reports that can be run across various Office365 surfaces but in this post I'm going to focus on the Mailbox related ones. Accessing Office365 Reports using Powershell is nothing new and has been available in the previous reporting endpoint  https://msdn.microsoft.com/en-us/library/office/jj984326.aspx however from the end of January many of these cmdlets are now being depreciated in favour of the Graph API  https://msdn.microsoft.com/en-us/library/office/dn387059.aspx . Prerequisites  In comparison to using the Remote PowerShell cmdlets where only the correct Office365 Admin permissions where needed, to use the new Graph API reports endpoint you need to use OAuth for authentication so this requires an Application Registration  https://developer.microsoft.com/en-us/graph/docs/concepts/auth_overview  that is then given the correct oAuth Grants to use the Reports EndPoin
