Mac Outlook 2011 – User is receiving all meeting invites for a different user

Good morning,

In our office we have a group of users who have Macs and have recently starting using Outlook 2011.

Our latest user was setup after all of the others as the secretary for another, and was given Editor status for the other's calendar.

Now all of the meeting requests sent to the second user are being forwarded to the newest user.

Any ideas as to why this might be occuring?

Thanks in advance!
