Litera, a dominant force in legal technology, pulled the trigger on June 3, 2026. Its Foundation 365 platform—a legal-specific customer relationship management system built on Microsoft Dynamics 365—now lives inside Microsoft 365, surfacing relationship intelligence directly within Copilot, Outlook, and Teams. The move smashes a long-standing silo between law firm CRMs and the productivity tools attorneys use every day.

Foundation 365 is already the CRM backbone for over 400 large and midsize law firms, managing client and matter relationships, business development pipelines, and cross-selling opportunities. Until now, that data stayed locked inside a browser-based interface. Attorneys had to alt-tab away from their email and collaboration tools to check client histories, matter statuses, or referral networks. That friction is now gone.

The headline feature is Copilot integration. Litera embedded Foundation 365 data into Microsoft’s AI assistant, so attorneys can query the CRM using natural language inside Word, Excel, PowerPoint, and the Copilot chat pane. Ask Copilot “What open matters does Acme Corp have with us?” and it pulls live data from Foundation 365, including matter descriptions, billing status, responsible partners, and recent interactions logged in the CRM. Copilot can also draft client summaries or prep emails informed by that data—without leaving the document.

Behind the scenes, Litera built a custom Microsoft Graph connector for Foundation 365. That connector indexes CRM records—contacts, companies, matters, activities, and relationships—and feeds them into the Microsoft 365 semantic index. Copilot then retrieves and grounds responses in that firm-specific data. The connector respects the CRM’s security model, so Copilot only surfaces information the user already has permission to see inside Foundation 365. A junior associate querying a matter won’t inadvertently see pitch data visible only to partners.

Outlook and Teams Become CRM Hubs

Outlook integration is equally deep. When a user opens an email from a client or prospect, a Foundation 365 sidebar appears in the reading pane. It shows the contact’s role, their company’s relationship tier, pending matters, recent activities, and the next step from the firm’s business development playbook. Users can log the email as an activity with one click, create a new matter from an email thread, or assign follow-up tasks that sync into the CRM.

For lawyers buried in email, this sidebar effectively becomes a constant CRM lens. No more switching contexts to check whether a contact’s company has a conflict or an overdue invoice. The sidebar also supports quick actions like adding contacts to a marketing list or scheduling a Teams call.

Inside Microsoft Teams, Foundation 365 adds a personal app and a tab for channels. The personal app aggregates daily briefings: upcoming client meetings, matter milestones, overdue tasks, and pipeline deals. A “relationship strength” score pulled from the CRM’s analytics engine helps attorneys prioritize outreach. The channel tab lets practice groups pin a shared view of their collective pipeline, recent wins, and client feedback scores. During Teams calls, the pop-out side panel displays participant relationship data, so nobody fumbles for basic client facts on a video call.

A Platform Years in the Making

Litera’s path to this integration started in 2022 when it acquired Foundation Software, a long-established provider of CRM for law firms. Foundation was already deeply invested in Microsoft’s ecosystem, with its CRM running on Dynamics 365 and its mobile apps built on Power Apps. Litera rebranded the product as Foundation 365 and accelerated the roadmap toward embedding it inside Office apps.

The June 2026 launch marks the completion of a multi-phase effort. Phase one, released in 2024, brought Foundation 365 data into SharePoint and Viva Topics. Phase two, in 2025, delivered a Power BI template for firm-wide analytics. The final phase ties it all together with the tri-app integration into Copilot, Outlook, and Teams.

“We’ve essentially turned every Microsoft 365 surface into a point-of-practice CRM experience,” said Haley Altman, Litera’s chief strategy officer, during the launch briefing. “Attorneys don’t want to learn another system. They want relationship intelligence where they already work. Now it’s in their email client, their collaboration hub, and their AI assistant.”

Real-World Impact on Law Firm Workflows

Legal tech consultants see immediate gains in adoption. Law firms have long struggled with CRM adoption because fee-earners resent data entry. By weaving CRM data into tools attorneys use for 80% of their day, Litera reduces the perceived overhead. An associate who logs an email from Outlook has effectively updated the CRM without leaving their inbox.

Business development teams benefit too. When a partner drafts a pitch in Word, Copilot can pull recent matter summaries, billing data, and team biographies from Foundation 365 to accelerate the first draft. Marketing professionals can build targeted email lists in Dynamics 365 Marketing based on relationship strength scores, then track engagement—clicks, RSVPs, replies—back inside the CRM. Those signals flow into the Outlook and Teams displays, alerting partners when a hot prospect engages.

There’s also a risk-mitigation angle. With Foundation 365 data available in Copilot, firms can build automated conflict-check prompts. Before a partner opens a new matter, Copilot can surface any past adverse relationships the firm has with opposing parties—data pulled from the CRM’s detailed entity records. Litera says it worked with several AmLaw 100 firms to refine the conflict-checking logic during a private preview that ran from January to May 2026.

Under the Hood: Architecture and Data Governance

Foundation 365’s Microsoft Graph connector is the technical linchpin. Litera engineered it to sync CRM records in near real-time, with an average latency under two minutes. The connector maps Dynamics 365 entities—accounts, contacts, matters, custom entities—to Microsoft Graph external items. Administrators configure which entity types and fields get indexed via the Microsoft 365 admin center. Fine-grained permissions flow from Dataverse security roles, so the connector doesn’t inadvertently widen access.

Data residency is a key concern for law firms. Litera confirmed that the Graph connector operates within the customer’s existing Microsoft 365 geo boundary. Indexed CRM data remains in the tenant’s sanctioned region; it isn’t copied to a separate Litera cloud. The connector itself runs as a service inside the customer’s Azure subscription, so data never transits through Litera infrastructure.

Licensing follows the standard Copilot model. Firms need Microsoft 365 Copilot licenses for users who will query Foundation 365 data via the AI. The Outlook and Teams integrations require Foundation 365 user subscriptions, which include the connector license. Firms on the Foundation 365 enterprise plan get the connector and all three integrations at no added cost; smaller firms on the professional plan pay a per-user monthly add-on fee, which Litera declined to disclose but said would be “under $30 per user.”

Competitive Landscape

Litera isn’t the first legal CRM to explore Microsoft 365 integration, but it’s the first to ship a full Copilot experience. Competitors like Intapp CRM (based on Salesforce) and Aderant’s CRM4Legal have offered Outlook add-ins for years. But those add-ins typically rely on client-side plugins that break during Office updates and don’t provide an AI layer. Intapp announced a Salesforce-Copilot connector in early 2026, but it remains in limited beta and lacks the native Teams experience Litera delivers today.

By building on Dynamics 365, Litera gains a structural advantage. Law firms that already operate inside the Microsoft cloud—using Azure, M365, Power Platform—can connect Foundation 365 without introducing a third-party SaaS that sits outside their tenant. This alignment with Microsoft’s roadmap also means Foundation 365 is first in line for Copilot enhancements like plugin support and autonomous agent integration, both expected in the Windows 11 2026 Update and Copilot for Microsoft 365 releases later this year.

Early Adopter Reactions

The private preview cohort offered measured enthusiasm. “The Outlook integration alone will save our associates fifteen minutes per client interaction,” said the CIO of an AmLaw 50 firm who requested anonymity because the firm hasn’t authorized public comment. “But the real test is whether Copilot’s answers are accurate enough for partners to trust without verifying. We’re optimistic but cautious.”

A common gripe during preview: data hygiene. If a firm’s Foundation 365 instance has duplicate contacts or stale matter data, those errors surface in Copilot responses. Litera bundled a set of data-cleaning tools—an AI-based deduplication engine and a “data confidence” score—to help firms prepare before enabling the connector. Consultants praised the tools but noted they add complexity to deployment. “It’s not a three-week flip-the-switch project,” one consultant said. “Plan for a three-month crawl, including cleaning, training, and change management.”

Future Roadmap

Litera’s event roadmap teases deeper Copilot capabilities. By Q4 2026, the firm plans to release a set of Copilot agents built on Foundation 365 data. One agent will compile pre-meeting briefs; another will suggest cross-selling opportunities based on matter patterns; a third will draft conflict waivers and engagement letters using CRM and document management data. These agents will run inside Business Chat, Microsoft’s enterprise chat experience, and can be scheduled to deliver daily reports into Teams channels.

Integration with Microsoft Viva Sales is also on the docket. That would connect Foundation 365’s pipeline data to Microsoft’s seller experience platform, giving law firm business developers AI-generated sales scripts, competitive intelligence, and relationship health indicators inside Outlook and Teams. Litera expects to deliver that integration in early 2027, pending certification from Microsoft.

On the mobile front, the existing Foundation 365 mobile app (Power Apps-based) gets a refresh later this month to surface the Copilot query pane and Teams integration notifications. Attorneys on the go can voice-query CRM data through the Copilot mobile app, with responses delivered in a conversational card format.

The legal industry has been slow to adopt AI-powered CRM, partly due to data sensitivity and partly due to user experience friction. Litera’s embedded approach—putting CRM intelligence in tools lawyers already inhabit—could reset adoption benchmarks. Analysts at Gartner and IDC have noted a broader shift toward “composable CRM,” where CRM functionality is distributed across multiple endpoints rather than confined to a standalone application. Foundation 365’s Copilot, Outlook, and Teams integrations are a textbook example of that architecture.

If the strategy pays off, expect other vertical CRM players—in accounting, engineering, and consulting—to follow suit. Microsoft’s Graph connector framework lowers the bar for any ISV to bring external data into Copilot, and Dynamics 365 provides a robust data model for professional services. Litera’s aggressive timeline may force competitors to accelerate their own Microsoft integration plans, ultimately benefiting law firms that want to reduce app sprawl.

For now, the message to legal IT leaders is clear: the CRM is no longer a separate system you log into. It’s a layer of intelligence woven into the fabric of daily work. And with Copilot acting as the query front-end, the days of lawyers complaining they “can’t find anything in the CRM” may finally be numbered.
