Original GitHub issue: https://github.com/aluxnimm/outlookcaldavsynchronizer/issues/272

In Outlook (2013), I can see more calendar items than is showing in NextCloud 15.0.14.
If I create a new CalDav resource, the new one has the same items in NC as the old one.
Why do I see more items in OL calendar and why won't they sync with NC?
What are the best settings to ensure OL syncs fully and properly with NC?

Of most significance is the calendar syncing at this time, but contacts and tasks have issues too.

NB: I cannot update NC at this time, not that I think that would make any difference here for this issue.

Nothing after all this time?

I'm starting again today with a client that syncs contacts perfectly well b/w two OL2013 and NC (NextCloud).

The OL2013 calendar on SOURCE machine has many items.
- there is only one calendar "Calendar (this computer only)"
Sync claims to succeed without errors
NextCloud calendar is empty.

To be safer right now, I am trying to sync from OL -> Server

How can I force syncing to work?

I've created brand new calendars and am going wit that, perhaps this is okay now.
