Hello,

I added meetings in my calander and send the invitations emails.

But Thunderbird did not recognize the attachted .ics File as caleder type.

I checked now another email, where Thunderbird show me "add to calendar" and there attached .ics file is defined as:

Content-Type: text/calendar; name="up2date_2017.ics"
Content-Description: up2date_2017.ics
Content-Disposition: attachment; filename="up2date_2017.ics"; size=3172;
	creation-date="Tue, 18 Apr 2017 09:00:41 GMT";
	modification-date="Tue, 18 Apr 2017 09:00:41 GMT"
Content-Transfer-Encoding: base64

But in the email, which odoo 10 send, is the attached .ics file as:

MIME-Version: 1.0
Content-Type: application/octet-stream; name="invitation.ics"
Content-Disposition: attachment; filename="invitation.ics"
Content-Transfer-Encoding: base64

So I guess, because of this, Thunderbird did not see the .ics as calendar event.

How can I fix this?

Thank you!
