"Some events were not shown in the calendars below because there were too many of them" Advisory Message in Team Calendars

[Scott Mosher]

All of our calendar items do appear on the calendar, but we still receive this warning/error advisory. Can you please disable that warning message from all of our team calendars? Or is there something I am missing here?

Its because, by default there are 200 events per calendar. You may set this to some other using the system value property .

"com.atlassian.confluence.extra.calendar3.display.events.calendar.maxpercalendar".

Add the below property to the end of the JAVA_OPTS section in the setenv.sh(if using LINUX) or setenv.bat (if using Windows)

-Dcom.atlassian.confluence.extra.calendar3.display.events.calendar.maxpercalendar=300
