Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Office 365 subscription does not include Ad-Free Outlook.com.
It does include OneDrive, Installing Office software on multiple devices, access to the latest Office apps and 60 Skype World minutes - but no Ad-Free Outlook.com.
I currently subscribe to Office 365 and also have a subscription to the Ad-Free Outlook here:

A part of me feels this is a cheap / sneaky way of monetizing something that is already being paid for, but then again, I do think I'm getting a good deal with the Office 365 subscription overall.
For Microsoft:
My suggestion for Microsoft is to make this information clearly available in the Outlook.com interface and the Users Account Settings. I would suggest modifying the Subscription portal to indicate Ad-Free Outlook as a separate subscription.
