Question

Finding the process of activating MS365 on my Mac incredibly confusing

Kevin Morrow 0

I just signed up for the $9.99 monthly MS365 subscription. I checked my PayPal account, and the payment has gone through, but I cannot for the life of me figure out how to activate the subscription so that I can edit my MS Office documents. I have a Mac. The help pages are telling me to open up my Word document and "sign in to Microsoft," which is something I've never been required to do, so I have no idea how to do that in MS Word. I also have tried clicking on the "Activate" button that shows up in MS Word, but then that takes me back to a page that asks me to sign up for the subscription I've already signed up for.

This is confusing as hell. Need help.

Well, like most answers I see in community bulletin boards like this, the prescribed fix is probably geared toward a version of MS Office I don't have. Nothing in the description looks like what I'm seeing. There's no "What's New in Office" box. I frankly don't even know how to start here.

I have a feeling something got really mucked in the process of signing up for this subscription because in the beginning, I signed for the "free" trial, only to find out that it blocked you from editing documents on your desktop, so I surrendered to the inevitable and got the monthly subscription. I wonder if that messed something up.

As stated in the article, you won't necessarily see the "What's new" welcome screen. Are you able to follow the alternative steps?

On Mac, activation is done by signing in inside an Office app with the Microsoft account that owns the Microsoft 365 subscription.

Open Finder > Applications.
Open Microsoft Word.
In the What’s New window, select Get Started.
On the Sign in to activate Office screen, select Sign in.
- If that screen does not appear, open a blank document and go to File > New from template > Sign in.
Enter the email address for the Microsoft account used to buy the Microsoft 365 subscription, then select Next.

If Word keeps sending activation back to a page asking to buy again, use this check first:

Sign in to https://account.microsoft.com/services.
Select Install Microsoft 365 or Office.
If the subscription is listed there, that is the correct Microsoft account to use in Word.

If no Office license appears there, the app is likely signed in with the wrong Microsoft account. Sign out in Word and sign in again with the account that shows the subscription.

If the subscription is a work or school subscription instead of a personal one, the license may not be set up yet by the organization’s administrator.

If activation still loops, old license data on the Mac can interfere. If multiple licenses were used before, remove the old Office license files on the Mac and then reactivate. This resets local activation data only; it does not remove the purchase.

If the apps were installed from the Mac App Store, reinstalling directly from the Microsoft account install page can help, because App Store versions typically require a Microsoft 365 subscription.
