Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Ok Sheri, you just gave quite some new information, and you do have quite a complex scenario there since you have three devices on three different OS versions.. This is why piggy back to others' threads will not get you the answer as yours is very unique.
The new information you just revealed here is - you have a subscription in your Microsoft account on Microsoft page. What this tells me is - you have one subscription you purchased directly from Microsoft (the old one), and the new one was via Apple. You previously said the old one was also purchased from Apple, that is what threw everyone off. A subscription purchased from Apple will NOT show up in your Msft account, vice versa. This is why your new subscription does NOT show up in your Microsoft account.
Now that we know how each subscription was purchased, I will talk about the download method. If you want to use the subscription from Microsoft, you need to download from Microsoft's website, NOT from the Apple App store. This is the very reason your reinstall didn't recognize your license purchased from Microsoft. And, if you want to use the subscription from your Apple App store, you must download from the App Store, that explains why the new subscription works, because you downloaded the apps from Apple App store.
In this case, I recommend you cancel the Apple one in your Apple account. But check with Apple's cancel and refund policy first to see if they allow you to cancel at this point.
The reason I recommend that you cancel the Apple one is because you have OS 12 and OS 13 devices. These two versions cannot run the latest Office apps properly. In order to get your Outlook to work, you need to get the downgraded/older version of Office apps. But only Microsoft provides the older version download, I don't think Apple does. And as I explained above, if you download from Microsoft, you want to use the subscription purchased from Microsoft (old subscription), not the one you purchased from Apple. Does that make sense?
If you do decide to go this route, let me know, I will assist you through the rest of the steps to reinstall on all three devices from Microsoft sources. They each need its own reinstall instructions, but don't worry, I will see through this whole process with you.
However, if Outlook is not the deal breaker here, you can certainly cancel the Microsoft subscription, stay where you are. Nothing further needs to be done.
