Microsoft Graph Contacts

Microsoft Graph Contacts is the part of Microsoft Graph that lets apps access and manage the contacts stored in Microsoft 365 (Outlook) mailboxes through a single REST API. It enables you to list, search, create, update, and delete contacts and contact folders for the signed-in user or other mailboxes you have permission to access, synchronize changes with delta queries, retrieve or update contact photos, and filter/sort results with OData queries. With delegated and application permissions controlled by Microsoft identity, it supports personal, shared, and delegated scenarios, making it easy to keep address books in sync and integrate contact data across Microsoft 365 services and devices.
