Microsoft Teams is a tool for communication and collaboration that is included in Office 365.

Among other features, it allows team members to share and collaborate on files with one another.

Fig. 1 shows the Microsoft Teams interface (with my organization's Teams, channel's and conversations covered up).

By default, each channel has a "Files" tab, as shown in Fig. 2.

The "Files" tab is a space for Team members to upload, download and share files with other members.

You have the ability to upload a file to this tab or to create a new file directly in this interface.

Create a New File

To create a new file, click the [New] button and select the type of file from the dropdown menu, as shown in Fig. 3.

At the next dialog, enter a name for your file, as shown in Fig. 4.

The file is created and displays within the tab. Fig. 5 shows an Excel file. Note that changes to the file are automatically saved. There is no reason to click a [Save] button.

If your organization uses Office 365, it is likely that you have access to Microsoft teams. If you do not, call your organization's IT department and ask them: "What's the problem?"
