Question

In our java springboot app we use dependency https://mvnrepository.com/artifact/com.microsoft.graph/microsoft-graph/5.72.0

When we try to create eventhub subscription for meeting room via that API we are getting error:

com.microsoft.graph.http.GraphServiceException: Error code: ExtensionError\nError message: Operation: Create; Exception: [Status Code: BadRequest; Reason: The value 'https://outlook.office365.com/api/v2.0/Users('Sandbox%40company.com')/Events'of parameter 'Resource' is invalid.]\n\nPOST[https://graph.microsoft.com/v1.0/subscriptions\nSdkVersion] : graph-java/v5.72.0\nSdkVersion : graph-java/v5.72.0\n[...]\n\n400 : \n[...]\n\n[Some information was truncated for brevity, enable debug logging for more details]

Sandbox%40company.com - I changed this intentionally, in the original response there is a different email.

But the error is only for particular emails, not for all. Other emails work fine.
