If you're looking to create a new meeting in Teams, take the following steps:
First, when Teams is opened, look along the left-hand side of the screen for the Calendar, as displayed below. When you find the Calendar, click to open it.
Once the Calendar is opened, your screen should look as displayed below. In the top right-hand corner, click “New Meeting.”
Next, your screen should look like the following. Fill in the sections needed for the meeting you’re creating. If you add recipients, as you type in a name, people should show up on a drop-down menu, from where you can select the correct people. You can choose the date and time, add a location, create a title, and add details in the notes. Once you have filled in the necessary spots, click “save” and an email will be sent out notifying anyone invited to the meeting. People will be able to RSVP or decline the meeting from the email sent out to them. The meeting will then appear on your calendar in the time slot you have selected.
