Updated March 7, 2023: We have updated the content below for clairty. Thank you for your patience.
We are introducing a default change for Excel Windows desktop apps that run XLL add-ins: XLL add-ins from untrusted locations will now be blocked by default.
For XLL add-ins in files from untrusted locations, you will no longer be able to enable content with a click of a button. A message will appear notifying you of the risk and a link to get more information about possible workarounds and support. This change will help you stay more secure by blocking popular attack techniques.
This message is associated with Microsoft 365 Roadmap ID 115485
[When this will happen:]
Preview: We have already completed rolling out to Insiders preview.
Standard Release: We will begin rolling out early March 2023 and expect to complete by late March 2023.
