As of October 1st, 2022 Microsoft will remove Basic Authentication to Exchange Online. See https://techcommunity.microsoft.com/t5/exchange-team-blog/basic-authentication-deprecation-in-exchange-online-september/ba-p/3609437. for additional details. Optionally, you can file a one-time request to extend the timeframe to January 2023 as outlined in the section “Opting Out”. To eliminate any disruption in service Poly recommends to take IMMEDIATE action to review your OTD configuration, in case you do use basic authentication/auto-registration.
If your OTD tenant is already integrated using OAuth and your video devices have calendaring service configured to authenticate using OTD generated credentials, no action is required from you at this time.
However, if your OTD tenant still has video devices with calendaring service configured in auto-registration mode (where O365 credentials are configured directly in the calendar settings of the Poly video device while pointing the server address setting to otd.plcm.vc), Poly recommends you to take IMMEDIATE ACTION and change your authentication type from auto-registration to OTD generated credentials model prior to upcoming October 1st. Detailed instructions on how to create a device, generate new device credentials and configure a Poly device can be found in our online documentation at https://otd.plcm.vc/support/docs/devices/registering-a-device. Failure to update the authorization type to OAuth and re-authorize the calendar integration will result in disruption of auto registration model for Poly endpoints to OTD which utilizes Basic Authorization at the time of deprecation.
It is recommended that any existing OTD configuration using auto registration migrate over to the service account or application identity models before the October 1st deadline set by Microsoft. It is highly recommended to no longer use automatic registration in any new deployments. Any organization setting up the OTD service with Exchange Online for the first time now should use the application identity model outlined in our online documentation at https://otd.plcm.vc/support/docs/calendars/office365-connect-as-application.
