Our subscription to "Add-in Express for .NET and VSTO" expired last week before we could renew. Would the expiration disable an Outlook add-in that is in production use?

Our Outlook add-in uses the Add-in Express library for core functionality.

Hello Roberto,

No, your subscription status doesn't affect your Add-in Express based add-ins. At https://www.add-in-express.com/purchase/subscription-comparison.php we use this wording: When your subscription expires, you can continue using the last version you obtained or are eligible to use.

Andrei,

Thank you, that was what I expected, but my boss wanted assurance.
