Switching from Microsoft 365 Copilot to Claude

Claude does not import Copilot chat history or Microsoft Graph grounding data — recreate any saved prompts and reconnect integrations manually.

Bottom line up front: When does moving from Copilot to Claude make sense?

When your team's heavy AI work is coding or long documents rather than Office files, because Claude Code comes in every Claude Team seat and some models take up to 1M tokens.

You give up Copilot's native grounding in Word, Excel, Outlook and Teams, and Claude reaches those tools through connectors instead. Price stops being a reason to stay after December 31, 2026, when Copilot's $18 reverts to $21 and Claude Team at $20 becomes the cheaper seat. You don't have to go all or nothing, though. Copilot Chat stays included with eligible Microsoft 365 plans, so a sensible setup is to drop the paid add-on, keep Chat for everyone, and put Claude seats only where the work justifies them. Run the same real task through both before you cancel, and save your prompts, since nothing imports.

    In every paid seat, no extra charge.

    No Microsoft 365 dependency

    Works with any office suite.

    Long context

    Up to 1M tokens on some models.

    How the migration actually works

    You lose Copilot’s native grounding in your organization’s Word, Excel, Outlook and Teams data — Claude reaches other tools only through separate connectors.

    StepWhat you do
    1Note what you actually useList the specific tasks (drafting, coding, analysis) and any custom instructions or saved prompts you rely on today.
    2Create your Claude Team workspaceCreate your Claude Team workspace and add seats (2-seat minimum).
    3Set up projects and connectorsRecreate any saved prompts or custom instructions, and connect the integrations (Google Workspace, Slack, GitHub) your team relies on.
    4Reconnect integrationsReconnect any connectors, add-ins or workspace integrations the new tool needs.
    5Train your team on the differencesRun the same task through both tools with a few teammates before rolling out broadly.
    6Cancel the old seatsOnce the team is comfortable in the new tool, cancel the old subscription or add-on.

    What this path doesn’t do for you:

    Copilot’s native, deep Microsoft Graph grounding has no Claude equivalent — Claude connects to other tools through connectors rather than native embedding.

    Before you cut over

    • Set up single sign-on in Claude on Team before you invite the team, so accounts are created through your identity provider rather than by hand.

Hover or tap “source” to see the exact wording we relied on. “Not published” means we could not find the vendor saying it on its own site; it doesn’t mean the feature is missing.

    Frequently Asked Questions

    Does Claude import my Copilot data?

    No, start fresh — recreate any custom instructions or saved prompts by hand.

    Will it cost more after 2026?

    No — once Copilot’s discount ends and it reverts to $21, Claude Team at $20 becomes the cheaper seat.

    Do I gain coding help?

    Yes — Claude Code is included in every paid seat, unlike Copilot at this tier.

    Does my chat history or custom assistants carry over?

    No. Conversation history, custom instructions and any saved assistants are specific to each platform and are not portable between them — start fresh in the new tool.
