Microsoft 365 Copilot + Box: What the Integration Can (and Can't) Do in 2026
Partly — Box ships two official Microsoft 365 Copilot integrations, but both are read-only. The newer one, the Box AI Agent for Microsoft 365 Copilot, is a third-party agent that lets Copilot search, summarize, and answer questions about your Box files — Box’s own docs say it “supports read-only actions such as search, summarization, and Q&A.” The older one, the Box Connector for Microsoft Graph, indexes shared Box content into Microsoft Graph so Copilot and Microsoft Search can ground answers in it. Neither writes back — Copilot can’t move a file, update metadata, or create a folder in Box through either path. And either way, everything happens inside a Copilot session you’re driving — nothing watches your Box account between chats.
Here’s what the two paths actually do, how to turn them on, where the ceiling is, and what to use if you want Box-adjacent work that runs on its own.
What Microsoft 365 Copilot can actually do with Box
Through the Box AI Agent (Box’s primary Copilot integration, a third-party agent powered by Box AI):
- Search, summarize, and Q&A over Box content without leaving Copilot — “instantly gain insights, summarize documents, and get answers to your questions” against files stored in Box. This initial release is read-only.
- Works wherever third-party agents are supported — Copilot Chat, Microsoft Teams, Word, Excel, and PowerPoint.
- Doesn’t burn Box AI units. Box states the integration “does not consume Box AI units,” and it’s included with all Business plans (Business Plus and lower tiers “may have additional considerations”).
Through the Box Connector for Microsoft Graph (the grounding/indexing path, one of Microsoft’s partner-built connectors):
- Ground Copilot answers in shared Box documents — “quickly synthesizing and summarizing shared Box documents to draw insights from collaborators,” with the source content surfaced.
- Surface Box content across Microsoft surfaces — the connector works within Microsoft Teams, at Microsoft365.com, and at copilot.microsoft.com, the same way any Copilot connector feeds Microsoft Search and Copilot.
Both are retrieval. The agent queries Box live; the connector indexes content into Graph for grounding and search. Neither creates, moves, or edits anything in Box.
How to set it up
The Box AI Agent is the lighter lift:
- Install the Box AI Agent for Microsoft 365 Copilot from the Agent Store (it appears wherever third-party agents are supported — Copilot Chat, Teams, Word, Excel, PowerPoint).
- Sign in and connect your Box account when prompted. If sign-in misbehaves, Box’s guidance is to uninstall and reinstall the agent from the Agent Store.
- A tenant admin can govern it — Box notes you can “navigate to the Microsoft 365 Admin Center and block the agent from the All Agents list” if you don’t want it available.
- Test it read-only: ask Copilot to summarize a shared Box document or pull the key points from a project folder.
The Box Connector for Microsoft Graph is a tenant/admin setup:
- You need a Microsoft Copilot license and a valid Microsoft tenant with an existing search quota.
- The connector “will need to be enabled by Box” — you complete Box’s request form to be enabled before you can configure it.
- Once enabled, it indexes shared Box content into Microsoft Graph so Copilot and Microsoft Search can ground answers in it.
The limits that matter
- Both paths are read-only. The agent does “search, summarization, and Q&A”; the connector indexes for grounding. Neither can upload a file, update metadata, move content between folders, or change sharing in Box.
- The connector must be turned on by Box. It isn’t self-serve — you request enablement from Box, and you need a Copilot license plus search quota on your tenant before it works.
- Plan gating on the agent. It’s included with Business plans, but Business Plus and lower tiers “may have additional considerations,” so what you get can depend on your Box plan.
- No triggers, ever. Neither the agent nor the connector fires on a Box event. Copilot answers when you prompt it. A contract can land in a Box folder, a deal-room file can get updated, or an approval can sit untouched over the weekend and nothing moves on its own.
- Session-bound and tenant-scoped. Every action needs a driver in a live Copilot session, and access is bounded by your tenant’s licensing and each user’s Box permissions. There’s no standing watch on your content.
If you want Box-adjacent work that runs on its own: Carly
The moment you want something to happen around Box without you in the chat — a new file in a client folder summarized and emailed to the owner, a signed contract filed and logged to your CRM, a weekly digest of what changed across a deal room, a Slack ping when a specific folder gets a new upload — you’ve crossed past what a grounding connector or a read-only agent is for.
That’s where Carly fits. Carly is an AI executive assistant built to act on triggers, not just answer in a session:
- Fires on events and schedules, 24/7, in the cloud. When a file lands in a Box folder or a document changes, Carly reacts — summarizes it, emails the owner, updates a task, posts to Slack — while your laptop is closed.
- Actually reads and writes. Box is a native Carly integration, so Carly can move and organize files, update records, and create tasks off what it finds — not just surface content in a chat.
- Sends, not just drafts. Carly drafts and sends email across Gmail and Outlook, books meetings, manages tasks, and records meetings — the follow-through that stops at the chat with Copilot.
- Builds the workflow by interviewing you. Tell Carly “when a new file appears in the Contracts folder, summarize it, email the account owner, and log it to the CRM” in plain English; it interviews you and builds it — no admin center, no connector enablement form, no prompt engineering.
Carly connects to 200+ tools across 40+ categories natively, plus any other tool via your own API key — paste it on carlyassistant.com/integrations. AI agents start at $35/month, and steps in a workflow that don’t use AI run free and unlimited. See integrations.

Frequently Asked Questions
Does Microsoft 365 Copilot work with Box?
Yes, for reading. Box ships two official integrations: the Box AI Agent for Microsoft 365 Copilot, a third-party agent that lets Copilot search, summarize, and answer questions about Box files, and the Box Connector for Microsoft Graph, which indexes shared Box content so Copilot and Microsoft Search can ground answers in it. Both are read-only.
Can Microsoft 365 Copilot upload files to Box or edit content in Box?
No. Box’s own docs describe the AI Agent as supporting “read-only actions such as search, summarization, and Q&A,” and the Graph connector only indexes content for grounding. Neither can upload a file, move content between folders, change metadata, or edit sharing in Box — you’d do that manually in Box.
How do I connect Copilot to Box?
For the Box AI Agent, install it from the Agent Store and sign in to your Box account; it works in Copilot Chat, Teams, Word, Excel, and PowerPoint and is included with Business plans. For the Box Connector for Microsoft Graph, you need a Microsoft Copilot license and a tenant with search quota, and the connector “will need to be enabled by Box” via their request form.
Can Copilot react to a new file in Box automatically?
No. Neither the Box AI Agent nor the Graph connector fires on Box events — Copilot only answers when you prompt it. For “when a file lands in this folder, summarize it and email the owner” or “digest what changed in the deal room every Monday,” you need a trigger-based assistant like Carly, which integrates natively with Box and runs in the cloud around the clock.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
