Hi to all,

we've a problem importing this ICS with Mac native Calendar (CalDav): others ICS files are fine, and if I modify this ICS without the UID tag, the ICS will load without problems.
We don't know if it's a CalDav problem.

Attached the ICS (renamed to TXT to upload in the forum) Aggiungi_in_agenda-24Jan20145238720911136820636 2.ics.txt
