[Evolution] Sending ical event invites to Outlook users?

[Kristian Rink <kawazu428 gmail com>]

Hi all;

sending around event invitations from within Evolution, I experienced
that Outlook users are for whichever reason unable to accept and add
these to their calendars. Is there anything on my side to be done about
that, or is this an Outlook specific issue?

Thanks,
Kristian
