Outlook Calendly Request Error: "Need Admin Approval"

Tags Calendly


When trying to integrate Calendly into Gannon email, users are getting an error: "Need admin approval. Calendly needs permission to access resources in your organization that only an admin can grant. Please ask an admin to grant permission to this app before you can use it."

More Information

  • ITS is not allowing access from 3rd party applications to our M365/Outlook environment. However, there are individuals on campus who are using the application another way without needing to get permission. However, it is inconvenient because Outlook must be running for it to work correctly. It is recommended that you use another program we have with Office 365: MS Bookings. It is already approved and works similar to Calendly, but even better.
    • Note: We are not taking individual requests for Booking sites for single users. Bookings requests are for departmental use only. Once a request is made for a Bookings site, each employee can have their own service request inside the booking site that is specific to them.
