sorry, I did not realize this is a duplicate of Issue #70
HTTP 403 error when syncing Calendars from mailbox.org
mailbox.org sends this:
<min-date-time xmlns=“urn:ietf:params:xml:ns:caldav” />
That means [https://tools.ietf.org/html/rfc4791#section-22.214.171.124]:
(CALDAV:min-date-time): The resource submitted in the PUT request, or targeted by a COPY or MOVE request, MUST have all of its iCalendar DATE or DATE-TIME property values (for each recurring instance) greater than or equal to the value of the CALDAV:min-date-time property value (Section 5.2.6) on the calendar collection where the resource will be stored;
The earliest time I can find in your event is:
so it seems the calendar doesn’t want events from 2016.
Can you enter such an event in the Web interface?
Thanks for the quick reply.
I imported my calendar events on my Android via an app called Calendar Import-Export and it contained events from long ago until now. Do you suggest I remove the older events and give sync a try again?
I didn’t enter any event from the Web interface.
