Outlook for Windows Signature cloud settings

Hi All,

Now it's finally have come true: Signatures from Outlook for Windows and OWA are shared.

M365 Roadmap Signature cloud settings

Let's check the Signatures on my Outlook for Windows Client

You can have multiple Signatures in Outlook

And they are now available in Exchange Online OWA

Sadly Outlook Mobile does not support it. Or not yet - don't know. But that would be much appreciated if signatures would be consistent across Clients.

It has been a long ride, as you can see here

Outlook for Windows - External Mails are marked better

Hi All,

It's been a while since i activated External Mails in Exchange Online
Set-ExternalInOutlook -Enabled $true

I have not updated my Office Version since last week.

But when i restarted Outlook today a saw a new "External" Tag in the Message Overview.
Seems to be there was a Change on 10. September 2022

On the Message itself - it's still the same Tip

In OWA nothing changed and it looks still the same

Hi All,

I have recently checked if there are new Drivers for my Surface Laptop 3.

I've checked in System Information

Exchange Server Zero-Day - Emergency Mitigation Service applied URL Rewrite

Hi All,

On 29. September Microsoft reported Zero-Day Vulnerabilities in Exchange Server and published the Advisory below.

Customer Guidance for Reported Zero-day Vulnerabilities in Microsoft Exchange Server

Customer Guidance for Reported Zero-day Vulnerabilities in Microsoft Exchange Server

I was wondering if the Exchange Server Emergency Mitigation Service kicked in. But until FR Evening 30 September there was just the default Rule

."C:\Program Files\Microsoft\Exchange Server\V15\scripts\Get-Mitigations.ps1"

When i checked today, a new Rule has been deployed

."C:\Program Files\Microsoft\Exchange Server\V15\scripts\Get-Mitigations.ps1"

You can see the Rule in the XML that is the base for the Mitigation Service

If you want to check the URL Rewrite here is how to do it


In my Opinion it took way to long until the Rule was published out to the Exchange Server Emergency Mitigation Service. Due to the fact, that there were seen such Attacs in the wild. Altough i appreciate the fact, that they are now available and help to Protect Customers from these Attacks.

For Systems that do not have the Exchange Server Emergency Mitigation Service Enabled or older Exchange Versions you can use the Script from Microsoft.

Exchange On-premises Mitigation Tool v2 (EOMTv2)

Microsoft.Graph PowerShell Module 1.12.2 released

Hi All,

A few hours ago, Microsoft has released a new Version of the Microsoft.Graph PowerShell Module.
Apparently it covers the latest API version and some minor fixes.

Let's check the installed Version and what's available on the 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. It takes a while until all Modules are installed. Wait until "Cleanup finished" is shown.

#Run Script directly from GitHub
$ScriptFromGitHub = Invoke-WebRequest ""
Invoke-Expression $($ScriptFromGitHub.Content)

Let's check

Get-InstalledModule Microsoft.Graph
Get-InstalledModule Microsoft.Graph*

M365 Apps for Enterprise got a slightly new Design

Hi All,

I've updated my Microsoft 365 Apps for Enterprise to 2209. There are several lightly new Designs to see...

Outlook has also a refreshed Design and shows Tasks and ToDo in the Navigation Pane on the left Top.

The ToDo does not work here

I like the new Design of OneNote

Microsoft Teams PowerShell Module 4.7.1-Preview with AzureAD App and Certificate Authentication

Hi All,

A few days ago the Microsoft Teams PowerShell Module 4.7.1-Preview was released. For me a long awaited Feature with Azure AD App Authentication with a Certificate is now partly possible.

MicrosoftTeams 4.7.1-preview

Microsoft Teams PowerShell Release Notes

Application-based authentication in Teams PowerShell Module

To install the Preview Side by Side with the  4.7.0 Module you need to add the -Force Parameter

Get-InstalledModule MicrosoftTeams
Find-Module MicrosoftTeams -AllowPrerelease
Install-Module MicrosoftTeams -AllowPrerelease -Force
Get-InstalledModule MicrosoftTeams -AllVersions

The following Permissions are Required for the Teams Commandlets
  • User.Read.All
  • Group.ReadWrite.All
  • AppCatalog.ReadWrite.All
  • TeamSettings.ReadWrite.All
  • Channel.Delete.All
  • ChannelSettings.ReadWrite.All
  • ChannelMember.ReadWrite.All

After you have addet the Permissions you need to Grant Admin Consent

For the *-CS Commandlets you need to add the Azure AD App to the "Skype for Business Administrators" Role

Now we are ready to connect

$AppID = "93b64305-ea5b-41f2-be0f-a2235fb91480" #DemoTeamsPS
$TenantId = ""
$CertificateThumbprint = "4F1C474F862679EC35650824F73903041E1E5742"

Import-Module MicrosoftTeams
Connect-MicrosoftTeams -ApplicationId $AppID -TenantId $TenantId -CertificateThumbprint $CertificateThumbprint

Some Test Commandlets

Get-CsOnlineUser -Identity | fl *Ent*,*host*,*voice*, *line*

For now only a few *-CS commandleds are working, but i guess soon the rest will follow

All Non *-Cs cmdlets (for example, Get-Team), Get-CsTenant, Get-CsOnlineUser, Get-CsOnlineVoiceUser & *-CsOnlineSipDomain cmdlets are already supported. Other cmdlets will be gradually rolled out.

For all other cmdlets you will receive an "Access Denied" Error Message
