We've identified the cause of the issue preventing users from adding Microsoft Teams as a video conferencing option when scheduling interviews on shared calendars. The Outlook API response for shared mailboxes is not returning any video conferencing providers, which results in the Teams option not appearing. At this time, it's unclear whether this reflects a change in how shared mailboxes are supported or if it is an unintended behavior. We recommend that affected customers work with their internal IT or Outlook support teams for further investigation.
