  • Connection data (e.g. phone numbers, country names, start and end times, IP addresses).

In the following we would like to inform you in more detail about the scope of data processing.

Required data and functions

As an employee, you may have a user account with which you as a "user" or "host" can organize and hold online meetings. To create your user account or to plan and hold an online meeting, the following data is collected and processed from you: name, user name, email or telephone number, password (if no single sign-on is used).

If you take part in an online meeting as an internal or external participant ("guest"), you will receive an access link from the host by email. When registering for the online meeting, you must then provide your name and, if applicable, your e-mail address. As a participant, you can take part in meetings directly from the browser without installing the Teams app.

If you use the chat, question or survey function, the text entries you have made are processed in order to display them in the "online meeting" and, if necessary, to record them. If you switch on your camera or microphone, the data from the microphone of your device and any video camera on the device will be processed for the duration of the meeting. When online meetings start, your camera image and microphone are switched off by default.

Please note that any information that you or others upload, provide or create during an online meeting will be processed at least for the duration of the meeting. This includes in particular chat / instant messages, files, whiteboards and other information that is shared while using the service.

If you take part in an online meeting as an external participant, your data will be processed on the basis of Article 6, Paragraph 1, Sentence 1, Letter b.

The same applies if the online meeting is necessary to carry out pre-contractual measures that are carried out at your request.

If the data processing in connection with the use of "teams" is neither necessary for the purposes of the employment relationship nor for the fulfillment of a contract concluded with you or for the implementation of pre-contractual measures, it is carried out on the basis of Article 6, Paragraph 1, Sentence 1, Letter f. GDPR. Our legitimate interest lies in maintaining location-independent communication, maintaining business contacts and providing the services owed.
