We have a strange incident on a user in using Outlook last week. When she
sent a meeting update to a list of attendees, three of them received it as
"Canceled:" instead of "Updated:". This is the first time I see this
happens. All recipients are in the same mailbox store, whereas the sender is
on a different store. We only have one Exchange Server 2003 for all
mailboxes.

Thanks
