Legal inboxes are different

Lawyers and paralegals handle dozens of matters at once. Each matter has its own folder, sometimes nested three or four levels deep. Manually filing each email costs real time, and misfiling creates real risk.

Without Folder Suggest

Scroll, guess, drag, repeat

You open a client email, scan the subject, try to remember the matter number, scroll through dozens of folders, and drag it into place. Multiply that across 80+ emails per day. Some emails end up in the wrong folder. Others never get filed at all, sitting in the inbox for weeks.

With Folder Suggest

Open the email. Click once. Done.

Folder Suggest reads the email content locally and surfaces the most likely matter folder at the top of a ranked list. You confirm with a single click. The whole interaction takes a few seconds. If the first suggestion is wrong, alternatives are listed below with confidence scores.

Zero-knowledge data security

Client confidentiality is non-negotiable. Folder Suggest was designed with that in mind. The AI model runs entirely inside your browser. No email subjects, no sender names, no message bodies are ever transmitted to an external server.

This is not a promise backed by a privacy policy alone. The architecture itself makes data leakage impossible. There is no server to send data to. The model file is downloaded once, cached in your browser, and every classification happens on your local device.

Built for how legal teams actually work

Different roles, same inbox problem. Here is how Folder Suggest fits into daily legal workflows.

1

Client correspondence by matter

An email arrives from opposing counsel referencing a case number. Folder Suggest matches it to the right matter folder based on content similarity to emails you have already filed there, not based on rigid sender rules that break when a new attorney joins the thread.

2

Discovery and privileged material

Emails tagged for discovery review or containing privileged material need to land in specific folders. Folder Suggest picks up on the language patterns in your existing filing and mirrors them. You still make the final call on every move.

3

Billing and retainer updates

Invoices, retainer renewal notices, and fee estimates arrive from multiple clients. Folder Suggest groups them correctly by client even when the sender email address is shared across a firm or when forwarded by a different contact.

4

Paralegal intake and triage

Paralegals who handle intake for multiple attorneys can file incoming correspondence without needing to memorise every matter number. Folder Suggest surfaces the most likely destination based on the email content, not the person filing it.

How it works

1

Open any matter email

Opposing counsel update, billing notice, court filing. Select the email and click "Folder Suggest" from the Outlook ribbon.

2

See the matter folder match

The add-in ranks your folders by content similarity to messages already filed there. The best match appears first with a confidence score.

3

File to the correct matter

Click once and the email moves. Choose a different folder from the ranked list if needed. An Undo button appears immediately after every move.

Questions from legal teams

Does Folder Suggest comply with attorney-client privilege requirements?
No email content is transmitted to any server. The AI model runs entirely in your browser, and classification happens locally. There is no external data processing, which means no third-party data exposure.
Can our IT department deploy it firm-wide?
Yes. IT admins can deploy Folder Suggest through the Microsoft 365 Admin Center, either from the Marketplace catalogue or by uploading the manifest file. It works across Outlook classic, New Outlook, and Outlook on the web. See the install guide for details.
How does it handle deep folder hierarchies?
Folder Suggest reads your entire folder tree, including deeply nested subfolders. It compares the current email against messages already stored in each folder, so even a folder buried four levels deep will surface at the top of the list when it is the best match.
Is it free?
Yes. Folder Suggest is completely free, with no paid tiers, no trial limits, and no account creation. Install it from the Microsoft Marketplace and use every feature without restrictions.
What happens if it suggests the wrong folder?
The suggestion list shows up to seven alternatives ranked by confidence. If the top match is incorrect, select a different option from the list. After every move, an Undo button appears immediately so you can reverse the action with one click.

Stop dragging. Start filing.

Free on the Microsoft Marketplace. Works in Outlook classic, Outlook on the web, and New Outlook for Windows.
