I have some problems. I'm trying to send an ics file, so an outlook user can add the event in his calendar. In some versions, like 2010, it works well (home edition) but on some, (like business) it doesn't recognize it directly. You must double-click the content so you can preview it. In that other version, it shows the calendar option immediately as I've clicked the mail.

What am I doing wrong?

Here is the code for the calendar.

$str="BEGIN:VCALENDAR\r\n

I am using swift class to send emails; Here are the settings:

$attachment = Swift_Attachment::newInstance()
                            ->setFilename("Invitatie.ics")
                            ->setContentType('text/calendar;method=REQUEST;charset=UTF-8;')
                            ->setBody($str)
                ->setDisposition("inline,filename=".$confDesc.".ics");
        $message2->attach($attachment);

  • The requirement to double click has little to do with the file content. That's for sure a client setting. – mario Aug 03 '11 at 14:50
  • You'd probably need to output a `header('Content-type: text/calendar')`, as an ICS file is just plain text anyways, which happens to contain calendar data. – Marc B Aug 03 '11 at 15:51

Be sure you added this header :

Content-Type: multipart/alternative;

And then for the ics file part : 

Content-Type: text/calendar; charset="utf-8"; name="testcal.ics" method=REQUEST'."\r\n";
Content-Disposition: inline; filename="testcal.ics"'."\r\n";

NB : \r\n MUST be between double quotes

is

DTEND:$endtime_ics\r\n

actually outputting the endtime or do you have some syntax missing?

also try validating the ics file at http://severinghaus.org/projects/icv/
