Summary:
The message details a planned update for Office on macOS, requiring Office add-ins and ODBC drivers to be codesigned with a valid Apple Developer ID. This change, expected in mid-November 2024, may affect workflows using unsigned dynamic libraries. Developers must ensure compliance, and admins should verify and prepare for this update.

Details:
Note: If your organization does not use macOS, you can safely disregard this message.
Microsoft Word, Excel, and PowerPoint in Office for macOS Version 16.91 only load dynamic libraries that are codesigned with a valid Apple Developer ID. As a result, Office add-ins or Open Database Connectivity (ODBC) drivers that rely on unsigned or ad-hoc-signed dynamic libraries don't work as intended.
However, most dynamic libraries used with Office apps are already codesigned, so this change is unlikely to affect most users.
In this message, when non-Microsoft products is mentioned, it specifically refers to products and applications that enhance or extend Office functionality (like add-ins or integrations). This doesn't include all non-Microsoft software installed on your device.
[When will this happen:]
This change is expected to be live in production in mid-November 2024.
