If someone declines your meeting invitation then, provided the person states a reason why they cannot attend, OfficeTalk will let you view their reason in the following way:
From the Meeting List view, select the meeting containing the member who has declined the meeting invitation.
Using the right mouse button, click on the member in the Member List and select Reason from the context sensitive menu.
ยท The Reason dialog box is displayed, showing any text that the responding member has entered. If the member has not left a reason, then you will not be able to show the Reason dialog box.
