Original GitHub issue: https://github.com/aluxnimm/outlookcaldavsynchronizer/issues/214

hello, I have a problem with the Caldav plugin for synchronizing a SOGo calendar with Outlook (both on outlook 2013 and outlook 2016).
In practice, when I create meetings and invite other people are created on the calendars of the people I invited the duplicate event.
People who receive the invitation to a meeting for a meeting accept it and then create a double event.

I currently use the latest available version of caldav (2.26.0.0).
I've put these settings but nothing changes:

"Conflict Resolution: Automatic"
"Synchronize items immediately after change"
"SET SCHEDULE-AGENT = CLIENT"

How do I fix this problem? I have all the people in the company who have this problem.
Is it enough to change some settings or do you need to fix the bug through an update?

p.s. sorry for bad english

Thank you

I have the same issue.
Win10 x64, Outlook 2019 x64, CalDav Sync 3.5.0 and Zimbra.

When I create an appointment, the invitations are sent out - normal behaviour.
As soon as the CalDav Sync runs the invitations are sent out again.
