An external user sends a meeting request to a Microsoft Exchange Server 2007 user who is using Microsoft Office Outlook 2003. In this situation, the meeting request is stamped as Busy
in the calendar of the Exchange Server 2007 user. However, the meeting request should be stamped as Tentative
until the Exchange Server 2007 user accepts or declines it.
This problem occurs because Exchange Server 2007 converts the meeting request from the iCalendar format to the MAPI format and sets the corresponding field to Busy
. Exchange Server 2007 does this because of the following line in iCalendar format.
However, Outlook 2003 directly uses this field value in the Show time as
field in calendar. Instead, Outlook 2007 converts a Busy
status to a Tentative
status. Therefore, this issue does not occurs for Outlook 2007.
