Filer includes a powerful algorithm that recommends folders where you are likely to file a selected email. Filer's folder recommendation algorithm learns your filing habits, so its recommendations become more accurate over time. In addition to improved filing consistency, folder recommendations also allow you to quickly file most email with a single click.

Filing related email—by conversation thread or by sender—typically requires the time-consuming and repetitive process of first sorting the message list and then selecting multiple messages. Filer allows you to quickly file email by thread or by sender from a single selection, often with a single click. Filer finds all related email and files each message for you, saving time and reducing filing errors. You can also have Filer automatically file all email from a sender, saving you additional time and steps.

Use Filer's snooze feature to temporarily remove lower priority email from your inbox for a chosen duration. After the snooze period, Filer returns the snoozed mail to your inbox in an unread state

Filer starts working the very next time you start Outlook. You don't need to configure or train Filer, and filer doesn't require that you create any complicated Outlook rules that then need to be maintained. Using Filer involves little more than clicking buttons or selecting menu commands. You can also customize the Filer toolbar to better match your filing style.

For Microsoft Office 2010 users, the Filer user interface is fully integrated with the Ribbon interface in Outlook 2010.

Filer's Topics feature allows you to group and track email from conversation threads of interest. Use Topics to stay current on important issues running through your inbox.

For users with deep folder hierarchies, avoid wasting time browsing the folder tree in Outlook's Navigation pane. Instead, use Filer's open folder feature to quickly search the Outlook folder list by name to open the folder in the Navigation pane.
