Documents Appear Black When Sharing Word Windows Using Microsoft Teams
What happens: When you share a Word window using Microsoft Teams, the people with whom you’re sharing see a black rectangle instead of your document.
What this means: Contract Tools uses an overlay to apply highlighting (see Highlighting Content) without changing your document. Microsoft Teams can cause this overlay to appear as a black rectangle when sharing a Word window.
What you should do: Share your desktop instead of a Word window, or turn off Contract Tools while sharing a Word window; see The Contract Tools Ribbon Tab to learn how to turn off Contract Tools. For help using Microsoft Teams, visit Microsoft Teams help & learning.
