Summary0005717: Email Header "References:" and reply mail

Mails can contain the header line "References:". Here's an example:
Message-ID: <DB9P189MB2123A61E97047399B363AC19AB879@DB9P189MB2123.EURP189.PROD.OUTLOOK.COM>
References: <DB9P189MB2123F50A0AED6EEC3B1E5FFDAB829@DB9P189MB2123.EURP189.PROD.OUTLOOK.COM>
In-Reply-To: <DB9P189MB2123ED885B8B355D9649FBB3AB819@DB9P189MB2123.EURP189.PROD.OUTLOOK.COM>

the "referneces:" line is displayed in the mail body when replying to a mail. I can delete this line. But this is not normal.

The "references:" header line can you find in mails over microsoft mailserver (, ...)

This is how the problem can be reproduced:

  1. i send a mail to a address. This mail has no "References" or "In-Reply-To" lines.
  2. the person reply to this mail.
  3. I receive the mail. This mail contains the lines "References" and "In-Reply-To"

Now, if i answer this mail: no problem. But if I forward the mail, the "References" line appears in the mail body.
I've attached a screenshot

Conclusion: the problem occurs only when forwarding a mail.
