We use Outlook 2003 Calendar to send notices for vacations, out of office, etc. How can we implement an "anonymous" calendar so that when a notice is sent, it does not indicate to the person (in their personal outlook calendar) sending the notice that they are out of office, but rather the person in the subject line?
Not sure if I understood what you want to do but I think the person sending the notice could schedule a meeting in her personal calendar and invite who she wants to the meeting without requiring their presence so they will have the notice in their calendars too. (Not sure if this is the result you want - who is the person in the subject line?).
EDIT: OK - I think I got it. The person sending the announcement is not the person taking vacation (or other notice). You could create an account "vacations" for example and let someone as assistant of it and send from this account (this way you can even have a global map of who is in vacations looking at the "vacations" calendar). I used to do this way for meeting rooms reservations in the past and I think this is a similar situation.
