Meetting response and Outlook

[MARNOW]

Hello,

When a calendar meeting is created in shared calendar, an automated message is send to all the attendees, required to be there, requesting a response of either accepting, rejecting, etc. the meeting.

When the attendee accepts or reject the invitation, the organizer of this meeting should get the notification "Yes, I will Attend" or No, I will not Attend" from every attendee, and she/he got it, but the Outlook 2007 show in the "From:" field that it has been sent by organizer not attendee. Thunderbird and webmail show it correctly. Does anybody is having this issues?

Outlook 2007 with ZCO 5.0.9

Thanks
Marnow
