Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello Graham Seal
Thank you for posting in Microsoft Community.
It seems like you have a short query about upgrading your subscription if you still need to pay for Outlook app. Let’s work together in finding the best answer to this issue.
The Microsoft 365 Personal subscription includes Outlook as part of its suite of applications, along with other popular Office apps like Word, Excel, PowerPoint, and OneNote. Therefore, you will only need to pay for the increased Microsoft 365 subscription, which will cover all the applications included in the Personal plan.
We look forward to your next response.
