Entries for recurring events are multiplied with each synchronization

We synchronized our Outlook Calendar with Confluence using Team Calendars and we are using the Team Calendars macro to share the calendar via a Confluence webpage but our calendar becomes saturated because every time Outlook synchronizes with Confluence, for every recurring event, a new entry is created in the calendar. The entries for recurring events are multiplied with each synchronization. How can we solve this problem?team_calendar_sync_outlook_problem_example.jpg

That's a gnarly issue. Are you using an .ics to view the data in Outlook or the new CalDav? 

I can't see any bugs that might be related to this, so to fix this we might need to dig into the database to remove the extra entries.

As a start, please make sure you're running the latest version of Team Cal first.


Hi James,

thank you for your reply.

We are using the new CalDav implementation and tend not to work with ICS files unless it's absolutely essential.

We are running version 6.0.20.



I've been going through other support tickets and recent Team Calendar bugs ( and I can't see anything similar.

We don't have many people on Outlook here so if possible, can you open a support ticket at so we can get really dig into this?
