Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
"I appear to have two subscriptions for MS365 when I only need one , how did this happen?"
I can't think of why someone would hack in to your Microsoft account and purchase a second subscription to Microsoft 365 for you :-)) Is it possible that you made some mistake along the way? (I myself have done much worse!) You can cancel the unneeded subscription and possibly receive a refund, depending on the circumstances.
