One of the more subtle improvements in Outlook 2003 is better handling of
conflicts that can occur when more than one edit takes place on a particular
item. Instead of showing the user a conflict item, Outlook makes its best
determination of which version to keep and shows the user that item, putting
any conflicting items in a Sync Issues\Conflicts folder in the mailbox. The
View Conflicts Size button on the Mailbox Cleanup dialog shows the user the
amount of space occupied by the Conflicts folder. The "Delete all alternate
versions" option clears the contents of the Conflicts folder.
