The easiest way to prevent students from joining your meeting ahead of time is to use the Meet Now option in your Teams Class when you're ready to start the meeting. Students won't see the Join button in their feed until you start the meeting. When you're finished, make sure to End the meeting rather than just Leave. This will prevent students from rejoining the meeting without you.

Another option is to use the Schedule a Meeting option. With this option, you must go to Meeting Options and change Who can bypass the lobby? to ONLY ME. This will prevent students from joining the meeting until you admit them from the lobby. 

See how to access Meeting Options in a "Meet Now" meeting the question below.

 First make sure you have updated the Teams app.  Once the meeting has started, choose Show participants icon in your meeting controls. You'll see a list of everyone in the meeting. Above the list, select Manage permissions "✔X " to go to Meeting options. Another way to get there during your meeting is to select More actions at the top of the meeting window, and then Meeting options. A panel will open on the right, and you can change your options right from there.

To share sound from your computer, select Share content Share screen button in your meeting controls and then Include computer sound—it's the switch on the top right of your sharing options. When you share, all audio from your computer, including notifications, will be included in the meeting.

First make sure you have updated the Teams app. 

To turn on the updated Teams meeting view settings: 

1. Open  MS Teams  and click on your profile icon at the upper right and select "Settings".  

2. Under Application select the checkbox next to "Turn on new meeting experience (New meetings and calls will open in separate windows. Requires restarting Teams.)"

3. Completely quit the MS Teams program and restart to relaunch the application. 

To switch views in a Teams meeting:

1. Start or join a Teams meeting. 

2. Make sure participants have their cameras on.  If you are seeing a few students and a bunch of circles with initials at the bottom, that means the students don’t have cameras on.  

3. Select the three dots "more" icon in the Teams meeting. 

4. Select either "Gallery" "Large Gallery" or "Together Mode" as your view.  NOTE: You must have enough participants to see alternate viewing modes.

Students must be Attendees in the meeting to prevent them from muting you or others, sharing their screen, and ending a meeting. 

On 8/15, Microsoft Teams was updated to automatically add students as Attendees (rather than Presenters) when they join a meeting. 

If you scheduled any meetings prior to 8/15, students will still be added as a Presenter. To see roles, click Participants (People icon) and the list will be divided into Presenters and Attendees. 

If a student is still a Presenter, simply click the 3 dots next to their name and make them an attendee.  Alternatively, go to Meeting Options and set Who can present? to Only Me. This will automatically make everyone else an attendee.  

You will be able to manually change those roles once the meeting starts if you needed.  So if you want a student to share his/her screen, you will click the 3 dots and make them a presenter for that time and then change him back. 

You can always change the join code to prevent additional students from accessing the class team. To change the join code: 

1. Go to Manage Team and select Settings tab at the top. 

2. Open the  section on Team Code and select to reset the code. 

Only students new to the Team will need it the new code. Make sure to change the meeting permission to force all students to wait in the lobby. See slides 34-40 of this presentation. 

You can log into Microsoft Stream and change the recording permissions  (to access permissions, go to  My Content, find the video, and then click the pencil icon and select the permissions you would like to share. 

However, since recordings in Stream expire after a certain time period, we recommend you download the video from Stream and upload to Google Drive (remember, you have unlimited storage space in Drive). You can then use the Share link to send to students or post in Seesaw or embed the video onto a Canvas page. Due to limited storage space in Canvas, we do not recommend uploading the video directly to it.
