Compliance: Emails von Gästen grundsätzlich als “Extern” in Outlook markieren

Seit der Ignite Anfang März 2021 ist es nun möglich externe Email zu markieren. Wie dies funktioniert erkläre ich euch in diesem Post:

Outlook mit “External ausstatten”

Dies hat den Vorteil, dass es zur Einhaltung der Compliance sehr gut ist. User erhalten so mobil, OWA und in Outlook (neuste Version) das Label External und sehen, dass die Email von Extern kommt. 

Damit kann dann der zusätzliche Header “Extern” per Nachrichtenrichtlinie entfallen. 

Voraussetzung

  • Exchange Online
  • nicht verfügbar für Exchange OnPremises
  • Exchange PS Module V2
  • Tenant muss die Funktion schon verfügbar sein, sonst kommt ein Error des PS Skriptes

unterstützte Versionen

  • Outlook on the web: available now
  • Outlook for Windows: available in May 2021 (starting with Insider Fast)
  • Outlook mobile (iOS & Android): version 4.2111.0 and higher
  • Outlook for Mac: version 16.47 and higher

Skript

ACHTUNG: Es ist noch nicht in allen Tenants ausgerollt!

Exchange Online – Tag for external email messages received
MC243047 · Published Mar 5, 2021
Message Summary

In this release, Exchange Online will enable admins to protect their organization against spam and phishing threats from external senders. This feature is available in Outlook on the web, the new Outlook for Mac, and Outlook mobile (iOS and Android).

This message is associated with Microsoft 365 Roadmap ID 70595.

When this will happen

This feature is available to be enabled now.

How this will affect your organization

Outlook will display a new tag on emails, External, in the message list. In some Outlook clients, the sender’s email address can be viewed at the top and will be included at the top of the reading pane or by clicking the External tag.

The External tag is available only in Outlook on the web, the new Outlook for Mac, Outlook for iOS, and Outlook for Android.

What you need to do to prepare

The External tag is off by default. If you want to enable the External tagging, use these PowerShell cmdlet instructions;

  • https://docs.microsoft.com/powershell/module/exchange/get-externalinoutlook
  • https://docs.microsoft.com/powershell/module/exchange/set-externalinoutlook

If you enable the cmdlet, within 24-48 hours, your users will start seeing a warning tag in email messages received from external sources (outside of your organization). In Outlook mobile, by tapping on the External tag at the top of the message, the user will see the email address of the sender.

You might want to notify your users about this new capability and update your training and documentation as appropriate.
