Microsoft Graph API Development & Office 365 Integration
Our Microsoft Graph API Development Expertise
SCAND provides Microsoft 365 (Office 365) integration services backed by 25+ years of software development experience. Since the 2010s, our team has worked with Office 365 REST APIs and Microsoft integration technologies, helping businesses connect collaboration tools, enterprise applications, and internal data sources.
Our Areas of Expertise:
- Microsoft Graph API and custom Graph connectors
- Outlook, Teams, SharePoint and OneDrive integration
- CRM, ERP and LMS integrations
- EWS to Microsoft Graph migration
- Microsoft Entra ID authentication and security
Office 365 Integration Services
Our Office 365 integration services on Microsoft Graph cover consulting, custom integrations, connectors, migration, and support.
Microsoft Graph API Consulting
We help organizations identify the most effective ways to use Microsoft Graph API based on their business goals, existing infrastructure, security requirements, and Microsoft 365 environment. Our consultants assess integration opportunities, define architecture approaches, plan permission models, and evaluate technical feasibility.
Custom Integrations with Business Systems (CRM, ERP, LMS, DMS)
Our developers connect Microsoft 365 with CRM, ERP, learning management systems, document management platforms, internal databases and third-party applications. We design integrations around the business events and records that matter to you, for example, associating Outlook correspondence with customer records, or making course and onboarding information available to the right employees.
Data Exchange Services
For those seeking to support interoperability between Microsoft 365 and external systems, we develop solutions that synchronize data across different platforms. Depending on business needs, we can implement live synchronization, scheduled data transfer, event-based integration, or bidirectional data exchange mechanisms.
Workflow and Approval Automation
We automate repetitive business processes across Microsoft 365 and enterprise systems using Microsoft Graph API. Our solutions support approval chains, employee onboarding, procurement requests, contract reviews, document routing, and notifications. By connecting the applications involved in each workflow, we reduce manual data entry, improve process visibility, and help teams complete routine tasks more efficiently.
Custom Graph Connectors for Microsoft Search and Copilot
We develop custom connectors that make information from external business applications, databases, and document repositories discoverable through supported Microsoft Search and Microsoft 365 Copilot experiences. Our services cover connector architecture, data source integration, schema mapping, indexing, identity and permission handling, deployment, and optimization. For advanced AI-powered knowledge discovery, we also provide Microsoft 365 Copilot development and RAG development services.
Teams, Outlook, SharePoint and OneDrive Integrations
We connect Microsoft Teams, Outlook, SharePoint, and OneDrive with business systems to support communication, document access, calendar synchronization, and information exchange. Depending on the requirements, an integration may synchronize meeting information with a scheduling system, associate files with business records, or send relevant operational updates to Teams. We can also extend Outlook through Outlook add-in development. Our SharePoint development expertise helps organizations extend SharePoint functionality and integrate it with existing business applications.
EWS to Microsoft Graph Migration
We help organizations modernize integrations that rely on Exchange Web Services (EWS) for Exchange Online. Our team audits legacy API calls, maps supported functionality to Microsoft Graph, reviews authentication and permissions, and implements and tests the replacement integration. Where Microsoft Graph does not provide equivalent functionality, we identify the gap and evaluate alternative approaches before migration. This work can form part of a broader legacy integration modernization strategy to improve compatibility with supported Microsoft technologies.
Security and Permission Management
We implement Microsoft Entra ID authentication, application and delegated permissions, and access controls tailored to each integration. Our developers apply the principle of least privilege, granting applications only the permissions required for their intended operations. We also account for consent requirements, token handling, role-based access, and organizational security policies.
Monitoring, Maintenance, and Optimization
We provide ongoing monitoring and support for Microsoft Graph API solutions, including performance tuning, error fixing, API usage optimization, and system updates. This keeps integrations stable as Microsoft 365 APIs and your systems change.
Moving from EWS to Microsoft Graph
Microsoft began disabling Exchange Web Services (EWS) in Exchange Online on October 1, 2026, and plans full disablement by April 2027. The transition may affect applications that use EWS to access Exchange Online mailbox data, including mail and calendar synchronization, archiving workflows, CRM connectors, and Outlook add-ins that use makeEwsRequestAsync. The exact impact depends on the application and the EWS operations it calls.
SCAND can help you assess the exposure and plan a migration in stages:
- Audit EWS usage in internal and third-party applications and identify affected operations.
- Map each operation to Microsoft Graph or another supported option, documenting capability gaps before committing to an approach.
- Review authentication and permissions, including Microsoft Entra ID, consent and single sign-on requirements.
- Refactor and test the integration, checking data handling, error recovery, access control and performance.
- Plan the production cutover, monitor results and retire the legacy path when appropriate.
