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....

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.

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....
