If you don't want the emails in your Microsoft Outlook Inbox with a luggage tag to be saved to iManage Work, set the Enable Inbox Filer option to false. Since none of the emails that you receive with the luggage tag are filed, the Filed to iManage label won't appear for them.

With the option set to true (default value), Inbox filer monitors all emails in your Inbox for a luggage tag and files them to the iManage Work location indicated by the luggage tag.

Example:

<key>Enable Inbox Filer</key>
<true/>
