Why teams connect Box and Microsoft 365

Land the records and documents that build up in Microsoft 365 into Box as they are created, and surface Box's file details on the Microsoft 365 records that point to them, without an export job to maintain.

Microsoft 365 and Box hold different kinds of data. Microsoft 365 carries records and the activity around them — the tickets, messages, orders, or issues a team works through, often with documents attached. Box holds files and the metadata that describes them. Where the two meet is narrow but real: much of what Microsoft 365 produces has to be kept somewhere durable, and many of the files Box stores are the very documents Microsoft 365's records point to.

Stacksync syncs Calendar Events, Contacts, OneDrive Files (driveItems), SharePoint Sites & Lists in Microsoft 365 with Collaborations, Users, Groups, Tasks in Box in real time. Records and attachments created in Microsoft 365 are written into Box as objects or files within seconds of being created. In the other direction, the metadata Box keeps about those files — name, location, owner, modified date — flows back onto the matching record in Microsoft 365, so people see the current document without leaving the tool. Field-level mapping controls exactly what crosses over and in which direction, so you keep a durable copy of what matters without an extract to schedule or a nightly dump that leaves the copy a day behind.

Common use cases

  • 01 Sync employee records from an HR system into Entra ID users and group memberships.
  • 02 Mirror calendar events into scheduling or CRM tools so meetings appear on customer timelines.
  • 03 Two-way sync of Files and Folders between Box and an operational database so applications track document status without calling the Box API directly.
  • 04 Mirror Metadata template instances on Files into database columns so contracts and assets are searchable and reportable alongside other business data.

Common sync patterns

A copy that outlives the tool

A continuously synced copy in Box preserves records and documents even as they age out of Microsoft 365 or get changed inside it, so history stays intact and reachable.

Feed a data lake or downstream pipeline

Structured records from Microsoft 365 land in Box as objects a data lake, search index, or processing pipeline can read, without a custom extract to build and babysit.

Archive what Microsoft 365 produces into Box

Records and events from Microsoft 365 — tickets, messages, orders, or issues — are written into Box as objects or files as they change, giving you a durable, addressable copy for retention and audit.

What you can sync between Box and Microsoft 365

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Box objects Microsoft 365 objects How this pairing syncs
Users Managed and app users in the enterprise; provisioned, updated, and deprovisioned to keep Box access aligned with an HR or identity source. Users Entra ID user accounts synced with HR and identity systems. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Groups Named user collections used for bulk collaboration; membership synced from a directory or IdP. Groups Microsoft 365 and security groups kept aligned with org structure and access rules. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Tasks Review or approval assignments on a file with due dates and states; read for workflow reporting or written to start approvals. Contacts Personal and org contacts kept consistent with CRM contact records. Tasks is specific to Box and Contacts to Microsoft 365 — each maps to any object or custom field on the other side.
Events Enterprise admin event stream, an audit log of uploads, deletes, logins, and shares across the account; read-only, consumed for reporting or change feeds. OneDrive Files (driveItems) File and folder metadata synced for document workflows and audits. Events is specific to Box and OneDrive Files (driveItems) to Microsoft 365 — each maps to any object or custom field on the other side.
Files Core content object with versions, name, size, and metadata; synced two-way so files and their attributes move between Box and a database or another store. SharePoint Sites & Lists List items read and written like lightweight database tables. Files is specific to Box and SharePoint Sites & Lists to Microsoft 365 — each maps to any object or custom field on the other side.
Folders Hierarchical containers whose tree, names, and parent moves are mirrored so a target system reflects Box's structure; the account root is always folder ID 0. Teams Team and membership data provisioned from upstream systems. Folders is specific to Box and Teams to Microsoft 365 — each maps to any object or custom field on the other side.

How changes propagate between Box and Microsoft 365

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Box Microsoft 365 Sub-second propagation

DetectionBox notifies Stacksync of record changes through webhook events. V2 webhooks fire on triggers such as FILE.UPLOADED, FILE.TRASHED, and METADATA_INSTANCE.UPDATED.

DeliveryEach detected change is written to Microsoft 365 through its API, with automatic retries and rate-limit backoff.

Microsoft 365 Box Sub-second propagation

DetectionMicrosoft 365 notifies Stacksync of record changes through webhook events. Graph change notifications (webhooks) plus delta queries for incremental sync.

DeliveryEach detected change is written to Box through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Box: Per user: 1,000 API calls per minute and 240 file uploads per minute; exceeding limits returns HTTP 429 with a Retry-After header. Box Business plans also carry a licensed monthly API-call allotment per enterprise.
