LEAP to Outlook_

Yes, LEAP connects to Outlook through a native add-in that allows fee earners to manually file emails against matters. The add-in works but requires manual selection for every email — a process that takes 30-60 seconds per message and is frequently skipped when fee earners are busy. Formulaic builds automated email filing that uses domain matching, subject line parsing, and client identification to file emails to the correct matter without manual intervention.

Short answer: Yes, LEAP has a basic Outlook integration for manual email filing. Formulaic builds automated filing using domain matching and subject parsing for hands-free matter association.

What data moves between LEAP and Outlook

Emails flow from Outlook to LEAP as matter-linked correspondence records. The email body, sender, recipients, date, subject line, and all attachments file against the matter. LEAP stores the email as a correspondence record with full metadata, making it searchable within the matter history.

Client contact data from LEAP informs the filing logic. The integration maps client email domains and individual addresses to active matters. When an email arrives from a known client domain, the system identifies which matter it relates to based on the domain, subject line references, and recent correspondence history.

Matter reference data helps with matching. Many law firms include matter references in email subject lines. The integration parses these references and matches directly to the LEAP matter record. For emails without explicit references, the system uses a combination of sender domain, recipient address, and subject line keywords to suggest or auto-file to the most likely matter.

Filing confirmation data flows back to the fee earner. When an email is automatically filed, a notification confirms the matter it was filed against. If the system is uncertain, it presents the top 2-3 matter suggestions for the fee earner to confirm with a single click.

The native integration

LEAP’s native Outlook add-in provides a sidebar in Outlook where fee earners can select a matter and file the current email. It works reliably and supports attachments. The limitation is that it is entirely manual — every email requires the fee earner to open the sidebar, search for the matter, and click to file.

In practice, this means that only important emails get filed consistently. Routine correspondence — status updates, scheduling emails, brief confirmations — often goes unfiled because the manual step feels disproportionate to the email’s apparent importance. Six months later, when the firm needs to reconstruct a matter timeline for a complaint or audit, those unfiled emails create gaps.

For small firms with simple caseloads, the manual approach is workable. For firms where regulatory compliance depends on complete correspondence records — which is most law firms — the gaps created by manual filing represent a real risk.

What Formulaic builds

Formulaic builds an automated email processing pipeline between the Microsoft Graph API (which controls Outlook) and LEAP’s API. The system processes incoming and outgoing emails and files them to matters without manual intervention.

Domain mapping links client email domains to LEAP matters. When the system sees an email from @smithandco.com, it checks which active matters involve Smith & Co as a client. If there is one active matter, it files automatically. If multiple matters exist for the same client, it uses subject line analysis and recent correspondence patterns to determine the correct one.

Subject line parsing extracts matter references, property addresses, and client names from email subjects. Law firms that use structured subject lines — “RE: [Matter Ref] Smith purchase of 42 High Street” — get near-perfect automatic filing rates.

Shared mailbox processing handles the firm’s communal inboxes. Emails arriving at info@, conveyancing@, or reception@ are processed against the same matching logic, ensuring that client correspondence received through shared addresses gets filed to the correct matter.

Confidence scoring determines whether the system files automatically or presents a suggestion. High-confidence matches (90%+) file without intervention. Lower-confidence matches present a brief notification with 2-3 matter suggestions. The system learns from the fee earner’s choices, improving accuracy over time.

Formulaic’s deployment data shows that automated email filing achieves 85-92% accuracy after the first month of operation, rising to 95%+ as the system learns the firm’s correspondence patterns.

FAQ

Can LEAP connect to Outlook? Yes. A native add-in handles manual filing. A custom build automates filing using domain matching, subject parsing, and client identification.

Does LEAP automatically file emails? Not with the native integration. A custom build files emails automatically based on sender domain, subject references, and correspondence patterns.

How much does a LEAP to Outlook integration cost? Every integration is custom-scoped based on your firm’s requirements. Start with an audit for a clear picture of cost and timeline.

How long does setup take? Two to three weeks. The build includes domain mapping, filing rule configuration, mailbox setup, and accuracy testing.

Does it handle shared mailboxes? Yes. Emails from shared addresses (info@, conveyancing@) are processed and filed to matters using the same matching logic as individual mailboxes.

How accurate is the automatic filing? 85-92% in the first month, improving to 95%+ as the system learns the firm’s correspondence patterns. Low-confidence matches present suggestions rather than filing automatically.

Does the integration preserve attachments? Yes. All attachments — documents, images, nested forwards — file with the email to the LEAP matter.

Can I override automatic filing decisions? Yes. Any automatically filed email can be refiled to a different matter. The system learns from corrections to improve future accuracy.
