Change from address on iPhone when using Mobile Sync

Change from address on iPhone when using Mobile Sync

Hi there

I've noticed that the from address (i.e. the part displayed in the recipients inbox) is set the the username when sending emails from iPhone via Mobile Sync.

Our naming convention is initials @ domain, so my emails are come from just "an".

Is there some way to configure it so the emails come from my full name?

Thanks
Adrian
