How to update your connected service settings in Microsoft Teams (free)

GIPHY and URL Preview are cloud-backed services are optional on Microsoft Teams (free). They're offered to you under terms that differ from the Microsoft Online Service Terms, as described separately for each optional service. You can remove the option to turn off cloud-backed services, including GIPHY, URL Preview, and more by updating your privacy settings. 
 
GIPHY allows you to use GIFs in your Teams chats. If you choose to use them, terms are subject to the GIPHY Privacy Policy and Terms of Service. 

The URL Preview service automatically generates a preview snippet and attaches under the snippet the URL when a user sends a URL string. This service will make a request to the service URL as the user is typing the message. If the service URL doesn't have any schema.org data, it will send a request to Bing search to get the data it needs to generate the preview snippet. Experiences that rely on Bing are licensed to you under the terms of the Microsoft Services Agreement and covered by the privacy statement. Any URLs you provide to Microsoft Teams while using these services can be sent to Microsoft Bing, including Bing Content Validation Service for evaluation of harmful content. They aren't linked to you by the Bing organization.
