I have a user who routinely sends Outlook calendar appointments (Outlook 2003) to other users within the company. Just recently (probably after a Microsoft update), her appointments started arriving as attachments rather than actual appointments that others can accept or decline.
In the attached version, the buttons labeld "Accept", "Tentative", "Decline", and "Propose New Time" are grayed out. In fact, all options under the "Action" menu are grayed out except "New Appointment".
I've looked under Tools > Options and nothing there seems to have any affect on it.
Anyone seen this before and know what's causing it?
