Original GitHub issue: https://github.com/aluxnimm/outlookcaldavsynchronizer/issues/223

Since the server upgrade to Nextcloud 13.0 the synchronization fails.
I am using version outlook 365 Pro Version1708 and outlookcaldavsynchronizer version 3.0.0

The error reported is:

The Server returns an Event with an invalid recurrence Pattern.
Probably the best approach is to delete it (or just the recurrence pattern) an create it new
