I have 5 different contact groups in outlook which I share with my staff. Each group serves a different purpose but the contacts within them overlap. One of them is uses my contacts, another uses a colleagues contacts etc. Each of us has our own contacts folder and we can share them between us.
I want a way to be able to send emails to group members in these groups, be they in my contacts or in a colleagues', while hiding the addresses of the rest of the recipients. Other than doing a mail merge through Word, is there a way to do this?
