I tested the Skype Meeting scheduler Add-in for Outlook 365 desktop-app and created some appointments. After testing I deleted the appointments, but all are shown in my Skype web scheduler, and I can not delete them there. Web scheduler says: "You can’t make changes to this meeting because it wasn’t created using Lync Web Scheduler."
Alle appointments were deleted in my calendar.
How do I delete them in the web scheduler?
Thank you for your help.
