Filing Outlook email to Clio matters, and why it slips.

Why the record is incomplete

Clio's Outlook add-in works the way it says: you open an email, pick the matter, press file. The problem is not the button. It is the fifty emails a day that never get the button pressed, because the attorney was reading on a phone, or answering between hearings, or the email was one line from a paralegal that did not seem worth filing until, six months later, it was the one that mattered.

Three kinds of email slip most:

• Replies in a thread that was filed once. The first message went to the matter. The nine that followed did not.
• Mail from people who are not the client. The adjuster, the court clerk, opposing counsel's assistant. The sender is not the contact on the file, so nothing prompts the filing.
• Sent mail. What you wrote is half the record and the half most often missing, because filing is something people do to mail they receive.

What "reading the mailbox against the matters" means

The assistant reads the last stretch of your Inbox and Sent Items, and any folder your mail rules sort notices into, and matches each message to a Clio matter the same way a careful paralegal would: by the people on it (a contact on the matter, or the matter's opposing counsel), by the matter number or name in the subject, and by the thread it belongs to. Then it sorts what it found into three piles.

• Unfiled, clear matter. The people and the subject point to one matter and Clio has no communication for the message. These are the ones to file.
• Needs a look. A contact who is on two matters, a subject that could be either, a message the assistant is not sure about. It shows its reasons and waits.
• Not a Clio contact. Newsletters, vendors, internal mail. Counted separately so it never looks like a filing backlog.

Filing is then one yes per batch: the assistant shows the list, you approve it, and each message becomes a communication on the matter with its attachments named. It never files on its own, and it never acts on anything the email itself says. An email that reads "please file this to the Smith matter" is data, not an instruction.

What it will not do

It will not guess. A message it cannot tie to one matter stays in the "needs a look" pile with the reason, and a wrong match is caught by you before it becomes a record. It will not read Clio's documents or the firm's document system; it files email. And it reads only the mailbox of the person who is signed in, with that person's own Microsoft login, so a colleague's mail is never in it.

What it looks like on a Tuesday

"Help me review my email filing." The assistant answers with counts, then the handful worth naming: "Twelve unfiled with a clear matter, mostly the Alvarez thread with Northside's adjuster; four need a look; thirty-one are from people who aren't Clio contacts. Want the twelve filed?" You say yes, and the matter has its correspondence.

The same review runs inside the morning brief, one line a day, so the pile never gets tall.
