If you are using the free or commercial versions of the popular Calendely solution, please immediately stop use. A vulnerability within their solutions is actively being leveraged by Ransomware attackers.
ITS would recommend leveraging the Microsoft Bookings solution as a replacement to Calendly. Booking is free and available within our https://portal.office.com environment. If you do not have the Bookings app, submit a ticket to the Help Desk.
