Microsoft Teams access policy - New-CsApplicationAccessPolicy returns 404

Question

I am trying to use the Microsoft Graph API to create OnlineMeetings here https://learn.microsoft.com/en-us/graph/api/application-post-onlinemeetings?view=graph-rest-1.0&tabs=http

But when configuring application access policy as instructed here:

https://learn.microsoft.com/en-us/graph/cloud-communication-online-meeting-application-access-policy

We got a 404 error:

New-CsApplicationAccessPolicy -Identity OnlineMeetings-Link -AppIds "xxx-xxx-xxx" -Description "xxxx Local"      

Get-CsOnlineSession: /Users/xxx/.local/share/powershell/Modules/MicrosoftTeams/2.3.1/netcoreapp3.1/SfBORemotePowershellModule.psm1:63

      | Cannot validate argument on parameter 'Session'. The argument

      | empty, and then try the command again.

I am an admin of the work/school account, and I have done all setup prerequisites:

https://learn.microsoft.com/en-us/microsoftteams/teams-powershell-install https://learn.microsoft.com/en-us/microsoft-365/enterprise/manage-skype-for-business-online-with-microsoft-365-powershell?view=o365-worldwide

I have all admin permissions to perform PowerShell cmdlet:

Environment:

PowerShell version: 7.1.3, installed with homebrew
MicrosoftTeams module version: 2.3.1
OS: Mac Mojave 10.14.6

I have no firewall, VPN/proxy enabled. The same issue happens when I tried it in the default PowerShell of Windows 10 VM on VirtualBox.

What should I do to get around this issue?

Answer 1

Upgrade the microsoft teams powershell module to 2.4.0 which is the latest version.

1. Connect-MicrosoftTeams #Enter global Administrator account credential and make sure that you see Admin account details in connection output.

2. Now execute the New-CsApplicationAccessPolicy

New-CsApplicationAccessPolicy -Identity OnlineMeetings-Link -AppIds "applicationID" -Description "description here".

To create a online meeting on behalf of a user in Microsoft Teams using Graph API there are two possiblities :

1. Create an event in teams by doing a Post https://graph.microsoft.com/v1.0/me/events and add properties "isOnlineMeeting":True and "onlineMeetingProvider":"teamsForBusiness" in the Body of the request.

   Sample:

    POST https://graph.microsoft.com/v1.0/me/events
Prefer: outlook.timezone="Pacific Standard Time"
Content-type: application/json

{
  "subject": "Meeting for New Member",
  "body": {
    "contentType": "HTML",
    "content": "Hello Team"
  },
  "start": {
      "dateTime": "2021-07-09T15:00:00",
      "timeZone": "Pacific Standard Time"
  },
  "end": {
      "dateTime": "2021-07-09T15:00:00",
      "timeZone": "Pacific Standard Time"
  },
  "location":{
      "displayName":"Virtual"
  },
  "attendees": [
    {
      "emailAddress": {
        "address":"user@contoso.onmicrosoft.com",
        "name": "User"
      },
      "type": "required"
    }
  ],
  "allowNewTimeProposals": true,
  "isOnlineMeeting": true,
  "onlineMeetingProvider": "teamsForBusiness"
}

If you use the above method then you can invite other users and the meeting appears in the calendar of the organizer.

2. Create Online Meeting

   You can directly create meeting by doing a post to POST https://graph.microsoft.com/v1.0/me/onlineMeetings

In the above method no invitations are sent and the meeting does not appear in the calendar of the organizer. You would need alternative means to distribute the dial-in link, etc.

Sample:

POST https://graph.microsoft.com/v1.0/me/onlineMeetings
Content-Type: application/json

{
  "startDateTime":"2021-07-09T14:30:34.2444915-05:30",
  "endDateTime":"2021-07-09T15:00:34.2464912-05:30",
  "subject":"User Token Meeting"
}

Answer 2

Looking at the error, the following could be the reasons

• Incorrect App ID or App ID does not exist
• Session parameter is empty

Request you to please check again and see if it works.
