Sent mail not shown in Sent mail folder

Sent mail not shown in Sent mail folder

Hello,

When I send an email that is part of a conversation, I have found that it doesn't appear in my Sent Mail folder. I have to find the conversation to see the mail that I sent. Is this expected behaviour? It makes it difficult to track down sent mails and is counter-intuitive for a Sent Mail folder. 

Regards,

Martin
