c# - What is required server-side to run Office Interops? -

i working on mvc4 website , add together interoperability ms office following:

communicator 2007 (presence status's only). outlook (to send template emails end-user's outlook). excel (to create info in excel sheet , save.)

is possible these office interop apis without installing office on hosting server?

are there alternatives interop provide same/similar functionality?

i understand security risks involved , microsoft's discouragement against server-side automation.

unfortunately, interops don't implement of office functionality, still need required office applications installed.

i'd @ using smtp sending emails, , npoi excel needs. avoid need outlook , excel on server. i'm not sure communicator.
