I am in a situation where I want to send email with iCal attachment to Outlook Calendar and I want to set reminder to 120 minutes before start event.
I send RAW message with iCal(see below). If recipient opens the message, event is automatically added to outlook calendar, but reminder is set to 15 minutes(default in outlook), even if I set different value in VALARM.
If I use ics file with iCal to import to Outlook Calendar then reminder is set to my value.
I would really appreciate help on this. How to set reminder for event?

I think there is nothing wrong with your code. Most calendar clients will ignore any alarm that is sent along with an invitation. When you think about it, this makes sense: if you invite me, I may want to accept or decline, but you should not dictate when I want to be notified.
On the other hand, when importing, you are making those events your own.
Change
METHOD:REQUESTtoMETHOD:PUBLISH. Also change your other method code at the bottom frommethod=REQUESTtomethod=PUBLISH.
