Replies to messages in my inbox are not visible to me.

I've send several replies to my team member's queries in my notificaions inbox, but I never see my replies in the message thread or in the sent folder.

I just sent one about 5 min ago to user 'skypher', and another one yesterday. I'm not sure the message went through at all, so I have to rely on a private email converstation (which is not always possible, since I may not know always know the email address).

Please look into this.

Thanks
