Microsoft OneDrive integration with MURAL is no longer be supported since October 28, 2021.
Here's how this may affect you:
OneDrive no longer appears as a file source (using the Files button) in murals.
Users can continue to use any existing OneDrive links in murals created prior to this date.
OneDrive can still be used in the canvas by sharing links. MURAL members can simply copy and paste the 'Share' link from OneDrive files into MURAL.
Permissions and access to OneDrive content are managed in your Microsoft OneDrive link settings. See this Microsoft support article for more information.
