title: Users added via graph not receiving welcome email
body: <p>First I tried adding a group owner as both owner and member in the same http call as I created the group:</p>
  
  <pre><code>{
    "description": "test group",
    "displayName": "test_group",
    "groupTypes": [
      "Unified"
    ],
    "mailEnabled": true,
    "mailNickname": "project.1-TestPreview",
    "members@odata.bind": [
      "https://graph.microsoft.com/v1.0/users/{id}"
    ],
    "owners@odata.bind": [
      "https://graph.microsoft.com/v1.0/users/{id}"
    ],
    "securityEnabled": false,
    "visibility": "private"
  }
  </code></pre>
  
  <p>The user is added as a member and owner successfully, but not receiving a welcome email.</p>
  
  <p>I then tried to split the http calls, thinking that there was an issue with the emails as the group was created at the same time as the user was added.</p>
  
  <p>I created the group with one user being added in the creation http call same as above and three other users being added as owner and member ~30 seconds after the group was created. For this I used</p>
  
  <p>queries:</p>
  
  <pre><code>{
    "type": "POST",
    "url": "https://graph.microsoft.com/v1.0/$batch"
  }
  </code></pre>
  
  <p>body</p>
  
  <pre><code>{
    "requests": [
      {
        "body": {
          "@odata.id": "https://graph.microsoft.com/v1.0/users/{id}"
        },
        "headers": {
          "Content-Type": "application/json"
        },
        "id": "1",

        },

        },
        "id": "3",
        "method": "POST",
        "url": "groups/{id}/members/$ref"
      }
    ]
  }

  <p>I added the users as owners with the same method. None of them received a welcome email. How can I make sure that the email fires? </p>
