Microsoft Teams – Connect to Powershell

Hi Guys,

Microsoft recently released the Powershell Cmdlets (still in beta), which gives you the opportunity to manage Microsoft Teams by Powershell.
To get started you wil first need to install the Microsoft Teams Powershell module. You can do this by using the following command:

Install-Module -Name MicrosoftTeams
<img class="alignnone size-full wp-image-1438" src="https://erwinbierens.com/wp-content/uploads/2017/11/install-module-MicrosoftTeams.png" alt="install-module MicrosoftTeams" width="809" height="89" />

After installing the module we need to set up a connection to your Office 365 tenant, using the following command:

Connect-MicrosoftTeams
<img class="alignnone size-large wp-image-1440" src="https://erwinbierens.com/wp-content/uploads/2017/11/connect-microsoftteams.png" alt="" width="388" height="120" />

When you are finished you can use the following command to shut down the connection:

Disconnect-MicrosoftTeams

In the next blog i will explain how to use the other commands to manage your Teams.

Microsoft Flow – Skype for Business Connector

I don’t know if you ever used Microsoft Flow, but i use it mostly for getting notification abouts some important rss feeds. In this example i will use a Weather forecast flow.

Microsoft released a new connector to send notifications to Skype for Business, (according to the microsoft docs site, it’s still in preview) you can choose 2 options:

  • Create an online meeting
  • Send an instant message

Create an online meeting

When creating the trigger meeting you can enter sip addresses separated by semi-colun.

in the result after running the Flow you can see the meeting URL created. When using Phone dial-in, confence ID, dial-in number and directory url will also be created.

In my test scenario the meeting did not popped up at my Skype for Business Client, so you will need to create another event to send the urls to the users.

Send an instant message

If you choose the IM option you can send a IM message to a specific user

You now will be notified about the Weather forecast (see top bar subject).

Limits

Connections per account: 2

Name Calls Renewal Period
API calls per connection 60 60 seconds
