What is Microsoft Teams?

Microsoft Teams is an application that allows you to easily create, share and collaborate as a team from a computer, tablet or mobile phone. It is therefore possible to combine group discussions, videoconference meetings, notes and attachments on a common platform.

The service integrates with Microsoft Office 365 and Skype, and offers extensions that can be integrated into a wide range of non-Microsost products. 

How to access it


You can do so in three ways:

First option, you should find the Microsoft Teams application in your program list (PC users provided by the School)

Security recommendations

Educate users about caution when adding members to Teams groups.

Teams group owners should be careful when granting access to a Team under their responsibility to avoid adding unnecessary members. A periodic review of the Team's members should be made.

Make users aware of the risks of using extensions and remind them of the importance of reading the conditions of use of an extension before installing and using it.

  • Install only extensions from the Microsoft store.
  • Pay attention to the permissions required for extensions. If an extension already installed on your computer asks for a new authorization, please review it carefully.
  • Read the terms of use carefully for each extension and ensure that they don't contravene school safety policies.

Educate users not to share very sensitive documents or data when using Teams.

Since the security level of Teams is considered to be medium, the participants in a group should avoid sharing or exchanging sensitive data (personal data on employees, students, passwords, etc.) via this channel and especially during the use of extensions. They can encrypt this data if necessary with the Winzip software and share the password by another channel if necessary.
