How to Install Microsoft 365 Apps or Cancel a Word Subscription on iMac

On an iMac M3, the answer depends on where the subscription was bought and which Microsoft 365 plan is attached to the account. This is an account-service task, so the key checks happen in Apple or Microsoft billing portals, not inside a local editor.

What needs to be confirmed first

Check whether the subscription is Microsoft 365 Personal, Family, or another offer. The available apps and billing controls depend on that plan.

Where it was purchased

A subscription bought in the App Store is managed by Apple. A subscription bought on Microsoft’s website is managed in the Microsoft account portal.

Whether redemption is required

If the product came with a redeemable entitlement, it must be attached to the Microsoft account before the full Office apps can be installed and activated.

How to get the other Office apps

If the subscription was purchased through Microsoft, install the suite from the Microsoft account dashboard instead of downloading Word, Excel, and PowerPoint one by one from the App Store.

Check the Microsoft account that owns the subscription

Sign in to Microsoft account and open Services and Subscriptions. If the plan appears there, that is the supported place to install the rest of the apps.

• Expected result: the subscription is listed under the signed-in account.
• If a key was provided, redeem it first at Where to enter your Office product key.

Use the Install option in Services and Subscriptions

When the product is visible in the Microsoft dashboard, click Install and download the installer package for the suite. This is the recommended path for getting Excel, PowerPoint, and the other included apps.

• Do not install each app separately from the Apple App Store if you want Microsoft account licensing to be detected cleanly.
• Verification: after installation, the apps should prompt for the same Microsoft account used for the subscription.

Supported entry point

Microsoft account dashboard is the supported web admin path for Microsoft-billed subscriptions.

App Store installs can create license-detection differences when mixed with Microsoft account activation.

The plan should appear under Services and Subscriptions before you expect the full app set to install.

Activation on Mac

If Office on macOS does not recognize the correct entitlement, Microsoft’s guidance is to remove old license files and then sign in again so the apps can detect the active subscription.

Run Microsoft’s Mac license removal guidance

Use the official article How to remove Office license files on a Mac. This is relevant when a previous Word install or mixed purchase path causes activation confusion.

• This does not cancel billing. It only helps the Mac detect the correct Office license.
• Expected result: after sign-in, the apps should request activation against the correct Microsoft account.

Reinstall or reopen Office and activate with the same account

After the license cleanup, sign in again and activate the Office apps with the Microsoft account that owns the subscription. This is the cleanest route if you are moving away from an App Store Word setup.

• Verification: Word, Excel, and PowerPoint should open as subscribed apps instead of asking for a separate purchase.
• Limitation: available documentation does not guarantee zero conflict when App Store and Microsoft licensing are mixed.

How cancellation works

Cancellation is controlled by the seller that billed the subscription. A local Mac app cannot directly change Microsoft or Apple cloud billing state.

If the subscription came from the App Store

Cancellation and refund questions must be handled through Apple or the original seller. Microsoft support cannot directly cancel an Apple-billed subscription from the Mac app.

If the subscription came from Microsoft

Use Microsoft’s official cancellation page: Cancel a Microsoft 365 subscription.

Pricing and subscription timing from the case

The source describes a free first month followed by monthly payments. It also notes that after cancellation, Word remained usable until Dec. 10, which indicates access can continue until the current paid or trial period ends.

• Billing model mentioned: first month free, then monthly subscription charges.
• After cancellation, service may remain active until the displayed end date rather than stopping immediately.
• Verification step: check the seller’s subscription page for the renewal status and expiration date.

The cleanest fix is to match billing, installation, and activation to one seller

If Microsoft billed the plan, install Office from the Microsoft account dashboard. If Apple billed the plan, cancel through Apple. On an iMac M3, mixing an App Store Word install with Microsoft 365 account activation can work unpredictably, so uninstalling the App Store version before moving to Microsoft 365 is the safer route.

The follow-up clarified that Word had been purchased through the App Store, then canceled. The remaining concern was whether buying Microsoft 365 afterward would conflict with the existing Word app on the iMac M3.

Will App Store Word conflict with Microsoft 365?

available documentation does not guarantee there will be no conflict. It explicitly says App Store licensing can cause errors during license detection, so mixing the two paths is not the preferred setup.

What is the recommended path?

The recommendation is to subscribe to Microsoft 365 Personal through Microsoft’s official website, uninstall the App Store version of Word, then reinstall and activate through the Microsoft account.

When Microsoft account help is needed

For account-specific billing or subscription issues, Microsoft’s answer points to chat support rather than public discussion. Use the exact web path below if the subscription is tied to Microsoft rather than Apple.

Go to Contact - Microsoft Support, type the issue in the search box, then choose Get help and Contact Support.

Under Products and services, choose Microsoft 365 and Office or another relevant product. Under Category, choose Manage My Subscription or the closest matching option, then confirm.

After confirmation, choose Chat with a support agent in the browser. Availability can depend on support hours, and phone callback may also be offered.

Where WPS Office fits in

WPS cannot cancel a Microsoft 365 or Apple subscription, redeem a Microsoft entitlement, or change cloud billing state for this issue. If you only need to keep working with local Word, Excel, PowerPoint, or PDF files while the account side is being sorted out, WPS Office is a lightweight option with a familiar interface, PDF tools, and WPS AI features for drafting, summarizing, and polishing documents.

Compatibility is generally good for DOCX, XLSX, PPTX, and PDF, but Microsoft-only cloud licensing, subscription status, and certain advanced Office features still need to be managed in Apple or Microsoft services.

Install Microsoft 365 Apps or Cancel a Word Subscription on iMac FAQs

Does a Microsoft 365 subscription on Mac include Excel and PowerPoint?

Microsoft 365 Personal and Family plans include the supported desktop Office apps for Mac. Confirm the exact plan and the Microsoft or Apple account that owns it before installing.

Where can I download the other Microsoft 365 apps for an iMac?

For a subscription bought from Microsoft, sign in to account.microsoft.com/services with the purchasing account and choose Install. Use Microsoft’s installer instead of downloading each app separately.

Why can separate Mac App Store Office apps cause activation confusion?

An App Store purchase and a Microsoft-direct subscription can use different billing and license paths. Mixing separately installed apps may make it unclear which account or seller controls activation.

How do I cancel the Word or Microsoft 365 subscription on Mac?

Cancel it through the seller that bills you. Use Apple subscription settings for an App Store purchase, or Services and subscriptions in the owning Microsoft account for a Microsoft purchase.
