Methods, systems, and computer storage media for providing a missing meeting content manifest associated with missing meeting content for a meeting (e.g., a meeting session) in a meeting management system. A missing meeting content manifest—a record of data of meeting content—can be a file that identifies segments of data that are associated with the missing meeting content. In operation, the meeting management system detects that an attendee is disconnected from the meeting and later determines that the attendee has reconnected to the meeting. The meeting management system calculates a number of segments of the meeting content associated with a period of time the attendee was so disconnected and generates a missing meeting content manifest corresponding to the number of segments of the meeting content associated with the period of time the attendee was disconnected. The meeting management system communicates the missing meeting content manifest to the attendee device.
