Add a calendar Entry to a OU's users calendar in Exchange 2010

We got a request from our business users  that they want to add a company event to users calendar.
As they do not want to send invitation to all the users, so I think it will require us to use Powershell script to do it.

May I know if anyone can provide the solution?

Our environment:
Exchange 2010 SP1 Rollup 3.
Windows 2008 AD servers.

1. Scope: Users mailboxes under an OU -
2. Action: Add a calendar entry to all the users calendars.
3. Title: Company Event.
4. Body: TBD.

If you need further information, please let me know.

    Thanks Rancy.

    Is there any possibility that we do not need to use EWS but Powershell only?
