Here are the latest news from Office 365, Teams, SharePoint Online and OneDrive:

prevent synchronization of content from other companies

Date: Mid June 2019

After June 17, 2019, it will be possible to synchronize content from other companies as well – provided they have been shared with you or the user. There will be a new setting to prevent this synchronization. This will only affect content that is shared with other companies.

Our recommendation: Consider whether you want to support or prevent the synchronization of content from other companies – and also whether you want to allow your users to access content from other companies at all. If you want to prevent access altogether, you can find more information here: Tenant Restrictions
