Displaying notifications for starting a session at a time that is different than a scheduled start time

A system comprising:

• one or more processing units;
• and
• a computer-readable medium having encoded thereon computer-executable instructions to cause the one or more processing units to:
• access schedule data that defines a scheduled start time for a communication session;
• access a notification parameter that defines a predefined join event for transmitting a notification configured to request that a first user associated with organizing the communication session join the communication session, wherein the predefined join event is associated with a second user, different from the first user associated with organizing the communication session, joining the communication session;
• determine, at a time that is before the scheduled start time, an occurrence of the predefined join event based on activity data representing a detected activity associated with the communication session;
• in response to determining the occurrence of the predefined join event, transmit the notification to a device associated with the first user associated with organizing the communication session, wherein the transmitted notification indicates that the second user has joined the communication session and the transmitted notification includes an embedded control that, when activated, causes the device to transmit a join request to join the device to the communication session before the scheduled start time;
• receive the join request from the device;
• and
• communicate, based on reception of the join request, data to the device to enable the first user associated with organizing the communication session to participate in the communication session before the scheduled start time.
