Legora Legal AI Integrates Microsoft 365, SharePoint and Azure OpenAI With Live Permission Checks

On October 14, 2026, legal AI vendor Legora (formerly known as Leya) announced a broad integration ecosystem aimed directly at ending that file-shuffling routine. Built around the company's Legora aOS ("agentic operating system") and the Legora Agent, the rollout comprises more than 30 integrations across nine enterprise technology categories, including direct hooks into Microsoft SharePoint, Microsoft Copilot, Outlook, and Teams alongside stalwarts of the legal software stack.

For enterprise IT administrators and Microsoft 365 architects supporting law firms or corporate legal departments, the pitch is straightforward: let AI agents read, redline, and route legal work across existing systems of record while inheriting the underlying permissions and ethical walls already configured by IT. Of course, in enterprise software, there is always a gap between a gleaming ecosystem map and what is actually wired up in your tenant on day one. Here is a closer look at what Legora is launching, how it fits into the Microsoft stack, and the governance questions IT leaders should ask before opening the API gates.

The "Download-Upload" Tax in Enterprise Legal Tech​

To understand why legal tech vendors are racing to build connector ecosystems, consider how legal work actually moves across a Windows desktop. A single matter rarely lives in one application. An intake request might arrive in Microsoft Teams or Outlook; the approved templates live in SharePoint or a dedicated document management system (DMS) like iManage or NetDocuments; deal documents sit inside a virtual data room (VDR); and the confidentiality rules dictating which lawyers are legally barred from seeing a file are enforced by third-party governance tools.

According to Bryan Tsao, Chief Product Officer at Legora, isolated AI drafting or contract review loses its value when lawyers have to constantly leave their workspace to hunt down files. Every excursion to another system chips away at the efficiency gains of generative AI. Worse, from an IT security perspective, exporting files from a governed repository to feed an external prompt creates "shadow files" that live outside the firm's access control lists.

Legora says its integration ecosystem is designed so the connected platform remains the authoritative system of record and the single source of truth for permissions, allowing legal teams to move a piece of work from initial request to final signature or billing entry without manual file transfers.

Breaking Down the Nine Integration Categories​

Legora organizes its 30-plus integrations across nine distinct layers of the enterprise legal stack:

Section Summary: Rather than offering a single generic file connector, Legora’s ecosystem spans nine functional categories—linking Microsoft 365 productivity and storage tools with specialized legal DMS, VDR, CLM, eDiscovery, and billing platforms.

Deep Dive: How Microsoft Azure and Microsoft 365 Fit In​

For WindowsForum readers, the most consequential piece of this announcement is how deeply Legora leans on the Microsoft stack—both at the infrastructure layer and at the user interface level.

According to a Microsoft Customer Story published in May 2025, Legora (which rebranded from Leya) built its platform on Microsoft Azure and Azure OpenAI Service after determining early on that calling raw OpenAI APIs directly would not satisfy the strict data privacy, security, and regional data-residency requirements of global law firms. Using Azure’s regional deployments allows the company to keep sensitive legal data within specific geographic boundaries, while relying on models such as GPT-4o and OpenAI o1 alongside Retrieval-Augmented Generation (RAG) and parallelized API calls for its Tabular Review feature.

On the client side, Legora is not just a standalone web app; its product lineup includes dedicated Microsoft Word and Microsoft Outlook add-ins, alongside connections to SharePoint, Microsoft Teams, and Microsoft Copilot.

• In Microsoft Word: As documented in Microsoft's case study, embedding Legora directly into Word allows attorneys to review and annotate agreements, summarize redlines, and generate issues lists inside their standard drafting window.
• In SharePoint and DMS: Dan Hendy, Global Legal Transform & Operate Lead at EY, noted in Legora’s launch announcement that connecting Legora to iManage, SharePoint, and Microsoft 365 allows EY teams to transition from locating documents to drafting and reviewing them without leaving the platform, with plans to extend those workflows into Datasite and Intralinks data rooms.
• In Outlook, Teams, and Copilot: By hooking into the communication layer, a lawyer can instruct the Legora Agent to pull a counterparty’s contract markup from an Outlook email, cross-reference it against approved precedent, redline the document, save the updated version back to the DMS, and log the billable hours automatically.

The Architecture of Trust: MCP, Ethical Walls, and Live Permission Checks​

Any CISO or Exchange administrator reading about an "agentic operating system" that reaches across email, SharePoint, and contract repositories will immediately ask a pointed question: How do we stop the AI from showing a junior associate the M&A files for a deal they are legally walled off from?

In law firms, ethical walls (information barriers) are not merely polite corporate guidelines; violating them can result in firm disqualification from a case or regulatory penalties. Legora’s product documentation outlines several architectural guardrails aimed at satisfying enterprise security teams:

1. No Cached Permissions: According to Legora’s integrations documentation, access rights are queried directly from the source system on every individual request rather than cached once during initial setup. If an administrator revokes a user’s access to a folder in iManage or SharePoint five minutes ago, the Legora Agent cannot retrieve that document for the user now.
2. Third-Party Ethical Wall Enforcement: Beyond standard file permissions, Legora integrates with Intapp Walls for AI and iManage Security Policy Manager. Matter-level confidentiality rules follow the documents into Legora and govern what the Agent is permitted to retrieve at each step of a multi-stage workflow.
3. Model Context Protocol (MCP) Connections: In its knowledge search tier, Legora highlights Model Context Protocol (MCP) connections to iManage and NetDocuments. As noted in an August 2026 company analysis by Contrary Research, Legora expanded its NetDocuments partnership using an MCP connection that allows the Agent to locate and utilize documents while respecting the firm’s existing access controls.
4. Audit Trails and Zero Model Training: Legora states on its product integration page that every read and write action executed through an integration is logged against both the specific user and the legal matter. The company also lists SOC 2 Type II, ISO 27001, ISO 42001, and GDPR compliance, and states that customer documents and prompts are never used to train AI models.

It is worth noting—with our veteran IT journalist hat firmly in place—that while these architectural controls sound music to a compliance officer's ears, the security guarantees, live permission checks, and audit logging descriptions come from Legora’s own documentation rather than an independent third-party technical audit of all 30 connectors.

Section Summary: Legora relies on Azure OpenAI Service for regional data residency and pairs its Microsoft 365 integrations with live per-request permission checks, MCP search connections, and ethical wall enforcement via Intapp and iManage.

Reading the Fine Print: Phased Rollouts and Asymmetric Capabilities​

When a software vendor announces "30+ integrations," enterprise buyers can easily assume that flipping a switch turns on uniform, two-way synchronization across all 30 platforms immediately. A closer inspection of Legora’s press release and product FAQ reveals important nuances that IT planners should keep in mind.

First, availability is phased. Legora explicitly states in its announcement that integrations have been rolling out to customers in phases since May 2026—such as its May 2026 Datasite VDR partnership, its August 2026 Box collaboration, and its October 2026 Sirion CLM partnership—and its product FAQ notes that general availability varies by integration. Similarly, as Law.com reported on October 13, 2026, when Legora launched its "Intake" agentic triage tool for in-house legal teams, that specific feature debuted initially in Slack with plans to expand later to email, Microsoft Teams, and MCP connections.

Second, data flow is not identical across every connector. Legora notes that some integrations pull partner content into Legora, some embed Legora’s capabilities inside the partner's interface, and only select integrations operate bi-directionally. Supported actions and accessible data fields depend heavily on the APIs of the host system.

Practical Checklist for Microsoft 365 and Legal IT Admins​

If your legal department or managing partners come knocking to connect Legora—or any similar agentic AI platform—into your Microsoft 365 and legal DMS environment, here is how to evaluate the deployment smoothly:

1. Verify Connector Availability and Directionality: Before promising a workflow to your attorneys, ask the vendor for the exact capability matrix for your stack. Confirm whether the Microsoft SharePoint, Teams, and Copilot connectors are generally available for your tenant region and whether they support read-only retrieval or full version write-back.
2. Test Per-Request Permission Inheritance: In a staging environment, test how the integration handles dynamic permission changes. Grant a test account access to a restricted SharePoint library or iManage workspace, run an agent query, revoke the permission in the source system, and immediately re-run the prompt to verify that access is blocked without token-caching delays.
3. Validate Ethical Wall Pass-Through: If your organization relies on Intapp Walls or iManage Security Policy Manager, verify how the AI agent behaves when asked a broad natural-language question (e.g., "Find our recent precedent on change-of-control clauses") where the best matching document sits behind an ethical wall for that specific user.
4. Review App Registrations and Audit Logs: Check how the Outlook and Word add-ins and the SharePoint/Teams connectors authenticate within Microsoft Entra ID, and confirm where the user-and-matter read/write audit logs are stored so your security operations center (SOC) can ingest them.

Agentic AI is rapidly outgrowing the isolated chatbot box. By wiring its platform into Microsoft 365, SharePoint, and the core repositories of the legal world, Legora is betting that the real winners in enterprise AI won't just have the smartest prompts—they will have the deepest plumbing.
