Thanks for reporting this. I can reproduce. I'll investigate.

Update: It's not limited to personal accounts. The SDK is not including the version segment in the URL. This URL is wrong:

https://graph.microsoft.com/me?%24select=displayName,mail,mailboxSettings,userPrincipalName

Between the graph.microsoft.com and the /me should be a version segment, /v1.0. The correct URL should be:

https://graph.microsoft.com/v1.0/me?%24select=displayName,mail,mailboxSettings,userPrincipalName

This appears to be an issue with the SDK. I'm finding out more from the engineering team.

Ok, so while they sort out this issue, here's a workaround. In GraphClientFactory.cs, change the line that creates the requestAdapter to:

var requestAdapter = new HttpClientRequestAdapter(
    new BlazorAuthProvider(accessor), null, null, httpClient)
        {
            BaseUrl = "https://graph.microsoft.com/v1.0"
        };
