If your Teams Exploratory Trial subscription expires, your customers who have installed your custom application from the App Store will still be able to use it.
However, they may not be able to access certain features of your application that require the Teams Exploratory Trial subscription. It's important to note that if you want to continue developing and publishing custom applications for Teams, you will need to have an active Teams subscription. Without a subscription, you won't be able to access the Teams App Studio or publish new applications to the App Store.
