Sunsetless
Free trial

Try Sunsetless EWS free for 14 days

Get a trial key for your Microsoft 365 tenant and run your existing EWS code on Microsoft Graph. No card, no call.

Where should the key work?

Find it in Microsoft Entra admin center → Overview → Tenant ID. The key works in this tenant only.

The trial is for testing; production use needs a license. By asking for a key you accept the Terms. We use your email address to send the code and the key: Privacy Policy.

How the trial works

  • The full library. The same NuGet package customers use, with every operation. Nothing is switched off.
  • One tenant, 14 days. The key is tied to the tenant ID you enter. A colleague who asks for the same tenant gets the same key.
  • Your data stays with you. The library runs inside your application and checks the key offline. It sends nothing to us.
  • No card, nothing to cancel. When the trial ends, buy a license and swap the key, or do nothing.
