As your team works together you'll undoubtedly have files that you'll want to share and collaborate on. Teams makes it easy to share Microsoft Office files and work on them together. If working in Word, Excel, or PowerPoint, your colleagues can even view, edit, and collaborate on them, right within Teams. If your team uses Google Docs, Sheets, or Slides, you can access those files when you add Google Drive as a cloud service. Clicking on a Google Drive link inside Microsoft Teams will open a new tab in which your team can view, edit, and collaborate with the correct sharing settings. You now have one place to put both Microsoft Office files and Google Drive files for your team to access.
Within each team there are channels. Think of these channels as a place for your entire team to discuss a specific topic, like upcoming training, or project updates. Each channel has its own file folder where you can share files for that specific channel. To access that folder go to the channel and select the Files tab above the conversation window.
Note: Make sure to use the Files tab at the top of the channel conversation window instead of the Files button on the left side of the app. That button gives you access to ALL of your cloud files, rather than just the files for a specific channel.
In the library, you can upload existing files or create new ones. When you upload a file, it creates a copy in Teams.
There are two primary ways to upload existing files into your library. Both methods start by going to the files folder for your channel and both methods, by default, upload copies of your files to the channel file folder.
Drag and drop - Using your mouse, drag the file from where it's currently located and drop it on the Teams window among the files.
Upload - Select Upload,then select the file (or files) you'd like to upload, and select Open.
Any files you upload will be accessible by any member of your team. And just like in SharePoint, you can pin specific files to the top of your list for easy access.
To create a Word, PowerPoint, or Excel document in Teams, select New, then select the kind of file you'd like to create. The new file will open in Teams so you can begin editing it, and if you'd prefer to work in the desktop version of the app, select Open in Desktop App at the top of the app, in the middle of the ribbon.
As soon as it's created your new file will be available for your team members to edit as well.
Files uploaded and shared to a team are accessible to every member of the Team. In Office for the web, Office for Android or iOS, or the latest applications from Microsoft 365, you and your team members can co-edit Word, PowerPoint, or Excel documents. No need to check files out or worry about if one of your colleagues has the document open. Just open the file you need to edit and if other team members are editing it too your changes will be seamlessly merged as you work.

If you're organizing a meeting with multiple attendees, you may want to assign roles to each participant to determine who can do what in the meeting. There are two roles to choose from: presenter and attendee. Presenters can do just about anything that needs doing in a meeting, while the role of an attendee is more controlled. Below are the specific capabilities of each role: Capability Organizer Presenter Attendee Speak and share video Participate in meeting chat Share content Privately view a PowerPoint file shared by someone else Take control of someone else's PowerPoint presentation Mute other participants Remove participants Admit people from the lobby Change the roles of other participants Start or stop recording You'll need to send out the meeting invite before you can assign roles. Once you've done that, go to Calendar This will bring you to a web page, where you'll see a few choices under Who can present? Who can present? What happens Everyone Anyone who has access to the meeting link will join the meeting as a presenter. People in my organization Only people in your org will be presenters. External participants will join as attendees. Specific people Only people you choose from the list of invitees will be presenters. Everyone else will join as attendees. Only me Only the organizer will be a presenter. All other participants will join as attendees. A couple of things to keep in mind: You'll need to send your meeting invite directly to anyone you want to select as a presenter. You won't be able to select someone from a different org as a presenter. Note: The ability to select specific presenters isn't yet available for channel meetings. There are two ways to change someone's role while a meeting is in progress: 1. Go to Calendar Note: If the meeting is recurring, any change you make in Meeting options will apply to all meeting occurrences. 2. Click Show participants in the meeting controls to see a list of the people in the people in the meeting. Hover over the name of the person whose role you want to change and click More options Notes: If the meeting is recurring, role assignments made in this way will only apply to the ongoing occurrence of the meeting. For future occurrences, participants will keep the role assigned to them on the Meeting options page. If someone exits the meeting and then rejoins it later, they'll rejoin with the last role they were assigned.

Collaborative teams build respect for each other's schedules when team meetings begin and end on time.
When given an exact time limit for completing meeting objectives, people are more likely to work harder to accomplish them. Keeping the time limit for online meetings one hour or below can help increase the effectiveness by helping to maintain attention.
In a group of 6 or more participants, everyone (except for the host) should start the online call muted and then toggle back and forth between mute and unmute as deemed appropriate. Toggling the mute/unmute feature is a necessary skill for many reasons:
Just like in-person meetings, there are some personalities that like to dominate the conversation and it could be challenging to hear everyone's opinion. Members in an online meeting can use the meeting chat to offer their insight without interrupting the speaker. All participants should keep their eye on new chat message alerts to ensure all voices are heard during collaboration.
Time is a precious commodity when gathering in a group for collaborative purposes. Please test your video/audio connections before the meeting in order to maximize productivity.
Grab the attention of a team member by "mentioning" them in the chat. Type the "@" symbol and begin typing their name. Press enter to accept.
The recipient will be notified that they were mentioned.
