Full Description:
On Sunday, September 25, 2022, Cornell will begin requiring that all Zoom account integrations with Office 365 calendars use the more secure OAuth 2.0 standard. This change is being made in anticipation of Microsoft’s upcoming deprecation of Basic Authentication (“Basic Auth”) on all Office 365 accounts.

Basic Auth was a simpler method of connecting to email and was significantly more vulnerable to malicious attacks on Cornell NetIDs and passwords. Microsoft is phasing out Basic Auth on October 1, 2022, to significantly improve the security of all email systems and accounts.

Please note that this change specifically affects the Calendar and Contacts Integration in a user’s Zoom profile. This integration, when enabled, allows a user’s Zoom desktop client to display meetings and contacts from their Outlook calendar. The upcoming change will *not* affect the Microsoft add-in for Zoom, which users may have installed in Outlook to allow them to easily add Zoom meetings while scheduling Outlook calendar events.

For more information, including how a user can check if their integration is using OAuth 2.0, visit the Cornell IT News article: Zoom Calendar and Contacts Integration Will No Longer Support Basic Authentication Starting September 25, 2022 .
