Beginning February 1, 2025, Microsoft's deprecation of Outlook legacy tokens resulting from a new authentication protocol, Nested App Authentication (NAA), may impact the Zoom for Outlook Add-in's ability to access Outlook calendar data.
To ensure continued functionality of the Zoom for Outlook add-in, on Friday, January 31, 2025, between 11:00am and 12:00pm, CIT will transition the add-in's authentication to NAA. Roll out of the latest version of the add-in to Cornell customers who do not already have it has already begun.
Effects on Customers
Zoom has reported to Cornell IT staff that these changes should not affect most customers. Some may be prompted to re-authenticate after the authentication method switches to NAA, though this occurs periodically during regular use anyhow. Users with an outdated version of the add-in may experience a temporary disruption until the most recent version of the add-in is automatically rolled out.
Impact on those still using the older Zoom Plug-in for Outlook is unknown, but these users are strongly encouraged to begin using the Zoom for Outlook add-in instead.
