We currently have clients running Outlook 2010 and within that we often have multiple mailbox accounts added. The additional mailboxes are set up as actual e-mail accounts (via Control Panel > Mail > E-mail Accounts). In Outlook 2010 this gives the end-user more functionality within the mailbox itself to manage rules etc without having to log into a separate PC or instance of Outlook.
Anyway, the issue we're having is that if a user has highlighted a secondary mailbox and they send an e-mail from it, the 'From' field in Outlook will default to the mailbox that is highlighted. What we are wanting to do, is to set the default 'From' field value to always be the user's default mailbox (i.e. their own account). I've browsed around and haven't been able to find a solution for this, or any reg settings that I could change to set this behaviour - so I would appreciate any assistance you can offer.
If you need further information/clarification, please let me know.
