Hi All,
With the August 2022 Updates for ExchangeServer 2013/2016/2019 there is a new Feature called Windows Server Extended Protection. This will help against authentication relay or "man in the middle" (MitM) attacks.
Exchange Server Support for Windows Extended Protection
- does not work with hybrid servers using Modern Hybrid configuration
- SSL Offloading scenarios are not supported
- Automated Archiving with Archive Policy is not suported
- TLS configuration must be consistent across all Exchange servers
- Access to Public Folders on Exchange 2013 not supported
The newest version of HealthChecker.ps1 does also support it. It will update automatically
After you restart the PowerShell Session and rerun HealthChecker.ps1 it will show you the Output for the IIS Modules and the VirtualDirectory
./HealthChecker.ps1
You can download the ExchangeExtendedProtectionManagement.ps1 from the Site below
ExchangeExtendedProtectionManagement
.\ExchangeExtendedProtectionManagement.ps1 -ShowExtendedProtection
Now let's enable Extended Protection
.\ExchangeExtendedProtectionManagement.ps1
Had to fix this
Set-OutlookAnywhere -Identity 'ICESRV06\RPC (Default Web Site)' -SSLOffloading $false -InternalClientsRequireSsl $true -E
xternalClientsRequireSsl $true
Let's try again
.\ExchangeExtendedProtectionManagement.ps1
Let's see what it looks like
.\ExchangeExtendedProtectionManagement.ps1 -ShowExtendedProtection
Let's again run HealhChecker and see the Results
./HealthChecker.ps1

Hi All,
Yesterday Microsoft has released the Version 1.11.0 of the Microsoft.Graph PowerShell Module.
Microsoft.Graph 1.11.0
Release Notes
Check the installed Version and what is availabe on PowerShell Gallery
Get-InstalledModule Microsoft.Graph
Find-Module Microsoft.Graph
To install the newest Version of the PowerShell Modules and also uninstalling the old Versions, you can use my GitHub Script
#Run Script directly from GitHub
$ScriptFromGitHub = Invoke-WebRequest "https://raw.githubusercontent.com/BohrenAn/GitHub_PowerShellScripts/main/ExchangeOnline/GraphAPI/Cleanup-GraphModules.ps1"
Invoke-Expression $($ScriptFromGitHub.Content)
It takes a while until everything is done. Wait until it shows "Cleanup finished"

Hi All,
I've tried out M365 Apps health
Microsoft 365 Apps health
https://docs.microsoft.com/en-us/deployoffice/admincenter/microsoft-365-apps-health
You have to go to the M365 Apps Admin Center
I've gone through the "Get started" Wizard
Selected a Group with my Office Devices
I've had to change the Office Channel to "MontlyEnterprise" to get some data
cd C:\Program Files\Common Files\microsoft shared\ClickToRun
OfficeC2RClient.exe /changesetting Channel=MonthlyEnterprise
OfficeC2RClient.exe /update user
After the Change i had to wait for several Hours
What do you think. Is this helpful?

Hi All,
I just want to write a short Blog Article about Exhange Online Protection (EOP) Malware Filter regarding the *.bin Attachments.
Just be aware, that when Adding Linked or Embedded Objects in Office Documents (like PowerPoint), the Objects are added as *.bin Objects and might be catched by the Malware Filter.
Import content from other applications into PowerPoint
If you rename the *.pptx or add *.zip at the end you can open in with Windows Explorer or any other ZIP Tool.
As you can see there is a "oleObject1.bin" File in the ppt\embeddings Folder
I have made a Test Anti-Malware Filter policy with just one Recipient addet.
The setting is to Reject a Mail with an NDR
And in the FileTypes there is *.bin
I send now a Mail to that Recipient with the PowerPoint that contains this Embeddet Object.
And i get an NDR
In the Details we can see that this was because of the Attachment and the Malware Filter.
As an Admin you can see that also in the Threat Explorer Details.
Regards
Andres Bohren
