APPLIES TO
- Microsoft Exchange Server 2003 Enterprise Edition
- Microsoft Exchange Server 2003 Standard Edition
SYMPTOMS
When an external message includes attachments that are .ics files, Microsoft Exchange Server 2003 converts all the .ics files to Microsoft Office Outlook items. If the .ics files are single-event iCal files, Exchange 2003 correctly converts the .ics files to Outlook meeting items that you can open. However, if the .ics files are multiple-event iCal files, Exchange 2003 is unable to convert the files. Therefore, all the .ics files are not converted to Outlook meeting items.
CAUSE
This problem occurs because Exchange 2003 unexpectedly converts the .ics files.
