[Petter Reinholdtsen] > Perhaps calypso only work with vCalendar items? I came across http://keithp.com/pipermail/calypso/2016-January/000089.html which contain a patch said to fix the vCard import.
I tested the patch and it seemed to solve my import issue. Perhaps it will be available in a newer version of calypso? -- Happy hacking Petter Reinholdtsen
