Apparently it’s not that easy to get the amount of members of a group with the Microsoft Graph API. We need to specify the additional header ConsistencyLevel: eventual to use the Advanced Query Capabilities. Then we can use the Query parameter $count. Alternatively I found that I could also add it as an URL query parameter instead. That would be &ConsistencyLevel=eventual. Example Queries Replace the Group ID (02bd9fd6-8f93-4758-87c3-1fb73740a315) with your desired Azure Active Directory Group ID....

Ich habe heute einen merkwürdigen Fehler beim Verbinden mit der Teams PowerShell erhalten. Ich notiere das hier kurz, da ich nach 15 Sekunden Internetrecherche keine Lösung dazu gefunden habe 😇. Alles was ich dazu spontan gefunden hatte, hatte nichts mit Teams zu tun. Ich wollte mich einfach nur per Connect-MicrosoftTeams mit der Microsoft Teams Administration per PowerShell verbinden. Ohne Angabe irgendwelcher weiteren Parameter, einfach ganz normal mit einem personalisierten Adminkonto anmelden und dann MFA bestätigen und so weiter....

This post is outdated. The “authentcation methods policy” is now easily available in the Entra portal. You might still need to migrate from the legacy settings, read the whole article at Microsoft Learn. OLD POST for reference In my opinion the official Microsoft Documentation lacks of any clear information on where to configure the allowed MFA methods for Azure AD. So if you’re also wondering on how to configure the allowed Multi-Factor-Authentication methods for Microsoft 365, you’ve come to right place....

Please note that this uses the older Azure AD Graph Module (already planned for deprecation)....

In neueren Microsoft Outlook Versionen es ist nicht mehr möglich, im Cache Modus für freigegebene Postfächer weitere E-Mails abzurufen. Stattdessen wird am Ende der E-Mail-Liste folgender Hinweis angezeigt: Es sind weitere Elemente in diesem Ordner auf dem Server vorhanden. Verbindung mit dem Server herstellen, um diese anzuzeigen In persönlichen Postfächern wird stattdessen die Möglichkeit geboten, weitere Elemente vom Server abzurufen. Der Text dazu wurde stümperhaft automatisch übersetzt, was sich gut ins Gesamtbild fügt:...

If you’re using Microsoft Booking in your Microsoft 365 Tenant, you might want to list all of the Booking calendars. Booking uses Exchange Online Mailboxes in the background. Every Booking Calendar has a corresponding Mailbox of the type “SchedulingMailbox”. If an user gets assigned “Administrator” for a Booking Calendar, they get “FullAccess” permissions for the Scheduling Mailbox. List all Booking Calendars with permission I wrote a PowerShell script to list all the Booking Mailboxes with the users that have access....

If you have Auto-Expanding Archives for Exchange Online Mailboxes enabled, you might want to find out, if it actually provisions additional storage. In the Exchange Admin Center (EAC), open the info pane of the user’s mailbox. Click on “Manage mailbox archive”. An Auto-Expanding Archive provisions more Archive storage space, if needed. Default Archives have 100 GB of storage available. If the archive is already bigger than 100 GB, we must have additional storage....

After creating SimpleIP.de as a serverless application (see my blog post My simple serverless journey was not that easy) I was kinda proud. Interesting technology, small and useful website. Nice. Reality But after a while reality kicked in. I was playing around with some IPv6 systems, when it hit me. With the previous design, the site would show only the primary IP-Address of the client. If the client supports both IPv6 and IPv4, it would still only show one IP-Address....

A short example for PowerShell Regular Expressions. Scenario: Match filenames like ID1234_MyDocumentXYZ.pdf.lnk.
