I am planning to buy a Microsoft Office subscription for my personal use. But is there any possibility that a Microsoft Office subscription expires after some time?
The validity of a Microsoft Office product depends on the category which you choose.
If you purchase licenced versions of Office Home & Student 2013, Office Home & Business 2013 or Office Professional 2013, you have to make a one-time payment for the license and can use it on one device. But if you are purchasing the Microsoft Office 365, you have to renew the subscription either on a monthly or a yearly basis and can use Office, simultaneously on up to 5 devices.
Before, buying a license for a Microsoft Office suite like Microsoft Office 2003, Microsoft Office 2007, and so on is good for lifetime. This is the more traditional way of buying Microsoft Office.
The license you buy is good only for the version you bought like if you buy Microsoft Office 2007, the license is good only for Microsoft Office 2007 and cannot be used on any other version like Microsoft Office 2003 or Microsoft Office 2013. But when Office 365 came, Microsoft offered another way of using their products by means of subscription.
With Office 365, you get to use the latest version of Microsoft Office for a monthly or yearly subscription. You can get access and use the latest Microsoft Office applications for as long as you pay the fee. Office 365 comes in different subscription plans: Home, Personal, Business, Business Premium, and Business Essentials. You can check the complete list of subscription plans on the Windows Store: Office 365.
