Buying Subscription

Generally, Apple will send a notification on iOS app subscriptions that will renew soon. However, we didn’t get any notification from Apple for the trail purchase from Mac App Store. Therefore, you need to ensure to disable the subscription if you don’t want to purchase the yearly subscription of Office 365.

During the trial period you can use all the feature of Office applications by signing to your Microsoft account including storing documents in OneDrive. At the end of trial period, Apple will charge you $69.9 and show “Purchased” when you look at the App Store.

Office application will work without any pop-up or warning during the trial period. After the trial ends, you will see a “Renew your subscription” notice inside the apps. It will show you the renewal date with a “Buy” notice that can’t be removed.

Difference Between Two Methods

Though, you can use one of the above methods to activate your subscription, it has some differences. Using the App Store apps will allow you to directly get updates from Apple. You can get updates whenever available like any other apps without the need of checking.

When you download the apps from, the installation package contains an auto component. By default, all the apps and the auto update is selected during installation. However, you can click on “Customize” button and select the apps. Ensure, you have selected and installed the auto update component when installing the apps.

Open any of the Office apps and go to “Help > Check for Updates”. You have three options for manually checking, automatically checking and automatically check and installing the updates. Select the required option and click on “Check for Updates” button. You will see the available updates for individual apps.

We recommend you using the Mac App Store version, since you can choose to install the app separately. Though it is possible to install individual apps from the package file, you first need to download the big package file. In addition, updating will be a problem with the apps as you may need to check manually. We don’t recommend the automatic checking as it will take time when you work on the app.

  1. There is a big problem with the activation if the subscription was purchased through Apple store. Office 365 license gets linked with Microsoft account and can be checked using the url or but if the subscription was purchased through Apple, you won’t find any license there on the Microsoft account page. When you would reinstall Office or if it would be deactivated after the trial, it won’t be possible to activate the product. Apple is playing this game from long time. They just charge the customer for yearly subscription and do not provide any product key or any license. Once the trial ends, they simply ask the customer to contact Microsoft and Microsoft has no idea about the customer’s license because it is not available in the customer’s Microsoft account and the order details are also not available with Microsoft because the purchase was made through Apple. So users get stuck.
