Grok for Microsoft 365: The Complete Picture (2026)
Between June 16 and July 21, 2026, xAI put Grok inside every major Office app. PowerPoint first, then Word, then Excel, then Outlook — plus connectors reaching Teams, SharePoint, and OneDrive from the chat side. It’s the most aggressive move any AI vendor has made against Microsoft on Microsoft’s own surface, and most of it is free.
Here’s the whole picture in one place, including the pricing split that the launch coverage keeps flattening.
What shipped, and what it costs
| Surface | Shipped | Price |
|---|---|---|
| Grok for PowerPoint | Jun 16, 2026 | Free M365 add-in |
| Grok for Word | Jun 18, 2026 | Free M365 add-in |
| Grok for Excel | Jul 20, 2026 | Free M365 add-in |
| Grok for Outlook | Jul 21, 2026 | Paid X or SuperGrok |
| Outlook Mail & Calendar connector | May 2026 | All Grok users |
| Teams, SharePoint, OneDrive connectors | May 2026 | All Grok users |
Three of the four add-ins are free. Outlook is the exception — xAI’s announcement puts it “available today to all paid X and SuperGrok users,” with no separate fee beyond that subscription.
Read the split as strategy. Documents and spreadsheets are where Grok is trying to make Copilot’s per-seat license look expensive. The inbox is where xAI thinks the willingness to pay actually is.
The add-ins, briefly
Excel — ask questions about a selected range and get answers that cite the cells they came from, describe a formula and have Grok write the syntax, run downside cases and forecasts. Edits land in the formula bar as normal edits, so the workbook stays readable without the add-in.
Word — notes into structured documents, drafts of proposals and guides, grammar and clarity rewrites, and style alignment across multiple authors. Web and X search plus diagram generation, from inside the document.
PowerPoint — outlines into full decks with research, diagrams, and images; add single slides, apply themes, restructure sections, tighten the narrative. It asks clarifying questions instead of guessing.
Outlook — thread summaries with decisions and owners, backlog sweeps that archive and junk and flag what needs a reply, and drafts in your voice from a few rough words. It reads attachments and searches web and X in place. Nothing sends until you hit send.
The connectors are the other half
Every add-in can call your Grok connectors, which is what makes this more than four separate chat panels. A Word document can draft from a SharePoint file. A deck can be built from something in Google Drive. A workbook can pull context from recent emails.
On the Microsoft side specifically, Grok’s built-in connectors cover Outlook Mail, Outlook Calendar, OneDrive, SharePoint, and Microsoft Teams — messages, channels, and chats.
The permission detail worth carrying: Outlook Mail requests Mail.ReadWrite and Mail.Send at sign-in, and Outlook Calendar requests Calendars.ReadWrite. Those are full read-write-send from the first Accept click, delegated to the signed-in user. Grok’s Gmail connector, by contrast, starts read-only and gains write and send scopes only when those tool groups are enabled. Microsoft accounts get the more permissive treatment.
Two setup gotchas: the connectors expect a Microsoft work or school account, and plenty of tenants require an Azure AD administrator to consent to the xAI Grok application under Enterprise applications first. If your sign-in dies on “need admin approval,” that’s the one.
Grok vs Copilot, honestly
The functional overlap is heavy enough that features aren’t the deciding factor. Three things are.
Cost. Copilot is a per-seat license on top of Microsoft 365. Three of Grok’s four add-ins are free, and the fourth rides a consumer subscription. For an individual, that’s not close.
Reach. Grok searches the web and X mid-task and pulls from Google Drive alongside SharePoint. Copilot is deep inside the Microsoft graph and doesn’t cross that boundary. If your work straddles Google and Microsoft — which a surprising number of small companies’ does — Grok covers both.
Governance. This is where it inverts. Copilot inherits the tenant’s compliance posture, data residency, and admin controls that IT already signed off on. Grok’s add-ins reach your data through OAuth grants individual users make, on a consumer subscription tier. xAI states it doesn’t train on connector data and doesn’t store mail or calendar content on its servers — but “the vendor says so” and “our DPA covers it” are different conversations, and for a regulated team the second one is the one that matters.
The rough rule: individuals and small teams should take Grok’s free add-ins seriously today. Enterprises should treat this as a procurement question, not an install.
What none of it does
The add-ins assist while the app is open. Close Excel and nothing happens in the workbook.
The bigger limit is what starts the work. Grok’s connectors reach a lot of apps and initiate nothing — they answer inside a conversation. On July 16, 2026 xAI shipped Automations, which changed that partly.
Grok is the first of the big assistants to react to an event rather than a clock — but the event is always an email. Automations fire on a schedule, or on an inbox match by sender, recipient, or subject, with the email-trigger tier reserved for SuperGrok. No other app can start one.
So across the whole Microsoft 365 footprint, Grok can react to one thing: an email arriving. Not the Teams mention, not the SharePoint file being updated, not the calendar invite being moved, not the Salesforce record changing — even though it has connectors to all of them.
The work that happens between apps
Most of what eats a working day isn’t inside a document. It’s the handoff: something changed in one system, and something needs to happen in another, and a person is the wire between them.
Carly is built for that wire. Agents fire on events across 200+ integrations — a record changing, a file landing, a form arriving, a date passing — and each one gets its own name and email address, so briefing it looks like emailing a colleague rather than opening a panel. Anything with a public API that isn’t already native connects with your own key. Free, unlimited Zapier-style workflows; AI agents from $35/month.
Grok’s add-ins make the time you spend inside Office apps shorter. That’s real, and it’s free, and it’s worth installing. It’s also a different problem from the one where nobody noticed for two days.
FAQ
Which Grok Microsoft 365 add-ins are free?
Excel, Word, and PowerPoint are free Microsoft 365 add-ins. Outlook requires a paid X or SuperGrok subscription, with no additional fee beyond it.
How do I install them?
All four come from the Microsoft Marketplace as Microsoft 365 add-ins, then appear under the Add-ins menu in each app. Connectors are separate and set up at grok.com/connectors.
Does Grok work with Microsoft Teams?
Through a connector, yes — Grok can reach Teams messages, channels, and chats from a conversation on grok.com. There’s no Teams add-in in the way there is for the four Office apps.
Do I need an admin to approve this?
For the add-ins, that depends on your tenant’s add-in policy. For the connectors, some organizations require an Azure AD administrator to consent to the xAI Grok application before users can sign in, and Grok Business and Enterprise require an admin to provision each connector in the cloud console first.
Is Grok safe to point at company email?
xAI states it doesn’t use Outlook mail or calendar data for training and doesn’t retain that data on its servers, with permissions delegated to the signed-in user only. Whether that’s sufficient is a policy question for your organization, not a technical one — and the Outlook connector holds send permission from the first sign-in.

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."
