Claude Cowork Meets SharePoint: What Legal Teams Need to Know About AI-Assisted Contract Review

A paralegal goes into a shared vendor agreement in SharePoint, looks for the indemnification clause, cannot find it in the expected place, and scrolls through the document. Forty minutes pass as she finally finds the clause in an addendum to the agreement. This forty minute occurs hundreds of times weekly in an average-sized legal department, repeated each time a contract needs to be found.

This is the exact problem that a Claude agent capable of reading an entire SharePoint document library, rather than answering a single pasted question, will address. Claude Cowork is the agent mode of Claude developed by Anthropic. Unlike Claude, this version of Claude is not engaged in a chat where it receives questions and answers them one-by-one but is assigned a task to complete with the defined scope of actions.

What Claude Cowork Actually Is

Claude Cowork works within the Claude desktop application and is designed to behave not as a chatbot but as an agent. The point is that you provide Claude with a task, and it then plans the actions, takes them, and informs you about what is happening at each step without waiting for another instruction after each of them. Claude can open the file, process it, extract information, and give output as an analysis, spreadsheet, or redlined draft, among other things.

The thing that makes it suitable for contract-based work: Claude Cowork can work in a Microsoft 365 environment, including SharePoint Online, using the Microsoft 365 connector provided by Anthropic. This means that Claude can process the documents from the library of your choosing, while you do not need to download them and upload again.

How the SharePoint Connection Actually Works

This is where it becomes necessary to be more specific about how the connection works because it’s easy to talk in generalities that make the situation sound more serious than it is.

Claude Cowork uses an optional connector to connect to Microsoft 365 SharePoint. In other words, the connection itself is not automatic but deliberate: the user or administrator has to choose to connect the Microsoft 365 connector and proceed with the OAuth authentication flow – the standard way to connect a third-party application to a Microsoft 365 tenant. In the course of that process, the user specifies which sites or folders they want to open for connection, and anything else is simply out of reach.

It follows that, first, permissions are granted directly by the customer; second, permissions are revocable. Revocation of the connector happens either in the settings of Claude itself or in the Microsoft 365 admin center, thus immediately disconnecting the connection and terminating any access. This point is clearly made in Anthropic’s documentation itself.

Cowork also seeks confirmation prior to executing any major tasks, unlike the process of editing or moving files without confirmation. For a legal department, this means choosing between an assistant who prompts a person to make a decision and a tool that silently makes changes to a file, which will later be signed by someone.

How does Claude Cowork connect to SharePoint?

A user or an IT administrator explicitly approves Anthropic's Microsoft 365 connector via OAuth flow, after which it is possible to choose specific SharePoint sites or folders to which Claude Cowork will have access. There is no automatic connection, no predefined scope, and everything can be disconnected at any moment from the settings of both Claude and Microsoft 365.

What This Means for Contract Review

Here are some of the practical applications once Cowork gains read access to a SharePoint library:

Clause and risk flagging: Aim it at a folder with vendor contracts and ask it to flag indemnity, limitations of liability, and termination clauses in there instead of spending hours poring over each of them in full.

Playbook Comparison: Provide it with your typical contract playbook, and ask it to compare against the redline coming in as a part of a negotiation, which would be the first step in any review process.

Preparation for Renewal: Get it to compile a summary of the contract's history, terms, and past points of contention before you have a renewal discussion with the other side instead of relying on your old email chains.

Reporting: Use it to generate a report from a bunch of scattered agreements in the form of a single document or a spreadsheet instead of having to prepare one by hand.

None of this replaces your judgement as an attorney. But it makes your first hour spent much more productive than going through forty PDFs.

What a Typical Session Looks Like

To put this into more concrete context, let us assume that a contracts manager has to prepare for the upcoming vendor renewal in three weeks. Rather than combing through the contents of the contracts folder on SharePoint, she gives one command to Cowork such as “search the contracts folder for this vendor, identify their payment terms and any requirements for the renewal notice, and mark anything that appears unusual.”

The program opens up the documents in the folder that has been the only access point provided to it and generates a brief summary together with exactly what it has found out in which place. Prior to making any changes to a document or saving anything, it first consults the contracts manager, who then reviews the summary, confirms what matters by opening up the actual contract, and heads for the renewal discussion with all her ducks in a row.

This is the way sessions with Cowork would look – a quick start-up process taking several minutes rather than hours, with the original document just one click away.

A couple of things to remember as you start incorporating this into the workflow process: it is a new technology, so it makes sense to start small before you go big with it; it only accesses the folders to which it has been explicitly granted access; and anything that it marks is just the beginning, not the end.

Getting Started Without Creating New Risk

Start small in terms of documents that you use – use a small, unclassified set of contracts and a limited task such as a clause review or a renewal summary – before you move on to anything else. Keep a human involved in the loop for all the decisions that actually need to be made, and also involve IT and Legal as part of the loop before you deploy the connection rather than after.

All of the above is true for any SharePoint library, irrespective of what governs it. But the value of the above connector lies in the data it is working with. Dock 365 is a Contract Lifecycle Management solution that is native to SharePoint Online, thus, contracts already contain relevant metadata such as contract type, counterparty, value, expiration date, rather than being just unstructured PDF documents in some folder. It is this very structure that enables any AI-based tool to provide actionable data rather than just guesses.
