Mailto hyperlink: How to SendAs / SendOnBehalfOf?

I am trying to make a hyperlink (in excel) for email, but cannot find any options for 'sendAs'.

=HYPERLINK("mailto:[email protected] & subject='Hello asdf'")

Is there an option in mailto, for a 'send-as' or 'send-on-behalf-of'?

Thanks.

Solution

  • Sorry, that was never designed into mailto. Here's the RFC syntax: https://www.rfc-editor.org/rfc/rfc6068#section-2

    The RFC does elude to an "In-Reply-" field, maybe you can use it to route responses.

    "An interesting use of 'mailto' URIs occurs when browsing archives of
messages.  A link can be provided that allows replying to a message
and conserving threading information.  This is done by adding an
In-Reply-To header field containing the Message-ID of the message
where the link is added, for example:

<mailto:[email protected]?In-Reply-To=%[email protected]%3E>
