I am trying to send an email with an calendar invitation from my system. I am using Nodemailer with AWS SES to send the email. However, when I receive the email, it is not recognized in Outlook or Apple Mail as it normally should. Instead the file is shown as an attachment like below. It works perfectly for Gmail.
My full mime email.

What can be wrong? I have tried everything, and read every article on the internet trying to figure this out.
The outer message content type is multipart/mixed. Outlook expects a single MIME text/calendar part that contains the calendar data.
I've faced a similar problem and solve it by rewriting a Content-Type header from
text/calendar; charset="utf-8";
to
text/calendar; charset="utf-8"; method=REQUEST
When I've added method=REQUEST to header, outlook started recognise my ics file as an event.

I'm trying to create e-mail with multipart/mixed content, with 2 HTML BodyParts (no attachments).

This e-mail renders fine in all clients even mobile ones I've tested except Outlook and Windows Mail. Seems like Microsoft's clients ignore the Second body part and displays only the Header before the main body part.
Is there any workaround? I don't want to create just one html content.
I am trying to send an email using Python. It works when I set a string as a HTML type MIMEText, but it doesn't work with the same string in PLAIN type MIMEText. The string is missing when I open the email. Following is a sample multipart message generated. What could be wrong?
Do I need to indicate that it is a Plain Text email so that email client can interprete it correctly?

I am sending an HTML email with an ical invitation attached.
I'm facing the issue that many mail-clients do not show the body of the mail properly.
Thunderbird shows neither the plain-text nor html e-mail body, only the raw invitation
Outlook 2013 seems to show the html-body but totally messed up. Only the raw text contained within the html-mail is shown. CSS seems to be ignored
This issue occurs only if the ical-attachment is present. If I send the same mail without the ical attachment, everything works fine.
Is there maybe some kind of header that tells mail-clients to also show the mail-body in addition to the ical-invitation or what else could I be missing?

I had a similar problem when sending ical Attachements from Rails and trying to check the resulting mails with MailCatcher.
The problem is the Content-Transfer-Encoding: 7bit (typically used for binary files) but your attachment is more like plain text.
Try to use quoted-printable instead, like in this example:
----==_mimepart_612e500330e6c_dd52137407244b
Content-Type: text/calendar;
charset=UTF-8
Content-Transfer-Encoding: quoted-printable
Content-Disposition: attachment;
filename=A-1105.ics

...
In Rails you can set the encoding when adding attachments like this:
attachments['mycalendar.ics'] = {
mime_type: "text/calendar",
encoding: "quoted-printable",
content: #ical_content_as_string
}
I am using java code to compose and send e-mail messages to MS Outlook 365 accounts.
The message is composed as following:
plain text part;
html part containing only table;
plain text part;
File attachment.
I expect that outlook displays part 1-3 as message body and the last part as attachment. Instead it displays only first part as message itself and puts the rest parts as separate attachments.
I have played with different headers, but result is the same. Is it some feature of MS stack (exchange, outlook, etc.) or I did something wrong?

------=_Part_0_2350964.1496689307498--
As a result I see only "Content before table" line, two attachments like "ATT01.html" and "ATT02.txt" and my original attachment "report.xls".
I have found one related topic at some forum saying that this problem should not appear since Outlook 2010 or so, but I can see it in the latest version both in desktop app and the web application.
The workaround solution to put everything in html part requires more work, because text parts are generated by other components.
You are grouping the parts incorrectly. It must be
1. Outer message, multipart/mixed
2. multipart/related
2.a text/plain
2.b text/html
3. attachment.
I'm trying to build up my own Email sending class and it seems I have a bug with my MIME.
If someone could find the error or tell me about a working MIME Validator I would really appreciate that.
Thanks in advance

There's a few things "wrong" with your email:
Firstly, you have a non-header in your header:
To: me#mydomain.com
*Test Alternate*
X-PHP-Originating-Script: 1000:SendMail.class.php
(*'s around the broken bit)
Secondly, (and probably your main issue with Thunderbird) is that your multipart/alternative has the child parts in the wrong order. The way that multipart/alternative is supposed to work is that the last part is supposed to be the form that is closest to what the original author of the message intended for you to see (IOW what he/she saw in their WYSIWYG editor).
TL;DR
Put the text/html part last and the text/plain part first within the multipart/alternative.
