Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I have the same issue, I already had a Family Microsoft 365 subscription, through Amazon.com that was set to expire on December 30, 2022. I just bought a new subscription that was available on Amazon (a prime day early access deal) and now I show a new subscription expiring on October 11, 2023, and my original subscription is still showing as expiring on December 30, 2022. I contacted Amazon support via chat and they told me they could not extend my original subscription a year to December 30, 2023 and my only option was to cancel the order I just put in for the subscription set to expire on October 11, 2023 and they would provide a full refund. Given that the prime deal was $42.95, instead of $99.99 for a 12-month subscription, I will not be cancelling the order. It is so unfortunately that Amazon's system managing your Microsoft Office 365 subscription has this limitation. I guess they are wanting everyone to just auto-renew at full price and cannot extend a subscription by buying it on sale. 😒
I have not activated the new subscription showing as expiring on October 11, 2023 yet, so I am wondering if I wait until December 29, 2022 to activate the new one (currently showing on October 11, 2023), and cancel the old one (which currently expires on December 30, 2022), I'm not sure what will happen.
