Conversations not being grouped properly
Hi I'm sending from a utility multiple related e-mails with different subjects. As these e-mails are related and there is one "main" e-mail and several "sub" e-mails, I want them to be shown in ...
Hi Bjorn,
I know this is an old thread, but did you ever find a way to make this work reliably?
I have a similar case. I send related e-mails from an application where all have the same subject. In-Reply-To, References and Thread-Index are set on every message, and the Thread-Index of each reply starts with the same 22 bytes as the first message.
They are grouped correctly in Gmail, Yahoo and Outlook on the phone. In classic Outlook for Windows on an IMAP account, they only group with Show as Conversations on, and even then they only appear as a list, not as one scrollable thread.
Did you change anything in the headers or did you find out what Outlook actually looks at when it groups messages?
Thank you!
P.S. Hope you found the solution :)
