365 add-in v. 4.0.1 (Microsoft 365 admin center > Integrated apps)

We have pushed the UI updates (no action required), which addresses the special characters issue with Outlook's 'classic' desktop version 2312.

It's a significant change due to the Microsoft bug reported on GitHub during the 2312 preview on 6 Dec, but still released by Microsoft on 4 Jan.

Manifest: v. 4.0.1

Outlook caches add-in JavaScript files.
How to clear the cache if the New/Reply email signature is not set automatically:

  1. Close Outlook.
  2. Delete everything in this folder:
    %LOCALAPPDATA%\Microsoft\Office\16.0\Wef\
  3. Open Outlook (wait ~5 min.)
