I recently imported an excel database of contacts into Outlook.

I want to do an email mail merge newsletter.
I click on Insert Merge Field however the Manager's Name field that I wish
to use is not available from the list displayed. Only the most common contact
fields are displayed.

Does anyone have any suggestions?

When I try to send my html newsletter from one computer it works ok and is
received ok (without doing a mail merge). However when I want to send it from
a different computer in our office the receipient only receives the
newsletter as text.
Please help. Suggestions are appeciated.
