If we create two or more events of the same event type, Team Calendars is likely to send a single email notification for them.

Requirements for this to happen:

• Start time must have a difference of less than 5 minutes
• The events must be on the same Calendar
• The event types must be the same
• The event must not be of the Event event type

Example:

1. Create one event of the type Travel set to 3:30 PM
2. Create another Travel event set to 3:33 PM
3. Create the last travel event set to 3:35 PM
4. Set reminders to 5 minutes before

Results :The notification for the events set at 3:30 and 3:33 PM is sent on the same email. The event set for 3:35 PM has its own email notification.

This is possibly related to this issue:

Suggested solution:

Improve the calendar job execution to be more granular so the reminders actually correspond to the settings. Or at least split the notifications in different emails.
