I think you pointed me in the right direction. 2.5.7 announces VPOLL for all except iOS/8 devices. HEAD doesn't announce VPOLL at all HEAD http_caldav.c:4520 /* Apple clients don't like VPOLL */ types &= ~CAL_COMP_VPOLL; vs. 2.5.7 http_caldav.c:3512 /* XXX iOS/8 doesn't like VPOLL */ if (hdr && strstr(hdr[0], "iOS/8")) types &= ~CAL_COMP_VPOLL; May I ask to backport this change to 2.5.x? I patched it locally and can confirm that our iOS/7 and 9 devices are able to access the Default Calendar now.
