Ok, weird one here.
We are running exchange 2003 with Outlook 2003 clients. Twice now I have had users tell me that they have sent an email to someone and that the email has also been sent to another of their contacts... but they did not add this recipient in to TO, CC or BCC field. It seems to have been randomly sent. When I look at the email in their SENT folder for sure, there is only the intended recipient listed and nothing else.
Any ideas as to what could be causing this?? Got me scratching my noggin! Thanks
