PowerShell's New-CsApplicationAccessPolicy not working

Question

Hi,

I am trying to use the OnlineMeetings API, but when configuring application access policy as instructed here:

https://docs.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

     | The remote server returned an error: (404) Not Found.

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

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

PowerShell version: 7.1.3, installed with homebrew

MicrosoftTeams module version: 2.3.1

OS: Mac Mojave 10.14.6

No firewall enabled.

What should I do to get around this issue?

Answer 1

Hi Nik,

Thanks for your suggestion. However, as I checked I am already the admin of the school, with Teams Administrator role along with the others.

Also, I have been using the latest version of both PowerShell (7.1) and MicrosoftTeam (2.4.0 preview), I've also tried with PowerShell 7.0 + Microsoft Teams 2.3.1 but in both cases I met the same error which is the 404 above.

I'm thinking of something else though if this problem didn't happen to everyone else. My location is in Vietnam right now, would it be an issue, like it is being blocked from here?

Answer 2

Also, ensure that you have e updated Microsft Teams module installed on the PowerShell:

Hi Hoang,

Thanks for your post on the community forum. I'm Nik, an independent advisor here to assist you with this.

To execute MS Teams PowerShell command, you'd need minimum Teams Administrator role on the Office 365 tenant.

To know more about Teams admin roles and capabilities

https://docs.microsoft.com/en-us/microsoftteams...

In this case, you'd need to contact your IT admin and request for the Teams Administrator role to manage the Teams service, and policies.

To know how to "Assign a user to an admin role from Active users", see https://docs.microsoft.com/en-us/microsoft-365/...

Answer 4

Hi Celso,

Thanks for your resource, it suggests me to enable permission to use the command. However, I'm quite new to this area and have no idea how to do that.

Is there any guide I could follow?
