Meeting requests from external senders are displayed as Busy instead of Tentative in an Exchange 2007 environment

SYMPTOMS

In a Microsoft Exchange 2007 environment, meeting requests sent by external users to users who are using Outlook 2003 clients are automatically stamped as Busy in the recipient’s calendar. Instead, such meeting requests should be stamped as Tentative until they are accepted or declined by the recipient.

Note You can determine the status by opening a meeting request and looking at the Show time as field.

CAUSE

This problem occurs because Exchange Server 2007 converts the meeting requests 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.

X-MICROSOFT-CDO-BUSYSTATUS:BUSY

Outlook 2003 directly uses this field value in the Show time as field in Calendar. However, Outlook 2007 converts a Busy status to a Tentative status.

WORKAROUND

To work around this problem, use Outlook 2007 as the client software.
