Do you know if this item from the Microsoft 365 roadmap would stop Add-ins (xll files) like this from working?

I also have a vested interest as one of my software products is an xll Add-in. Any further details from Microsoft would be most welcome, thanks.

No idea, haven't seen this until now. Hopefully they provide a mechanism for allowing legitimate addins to get around it. Perhaps using a code signing cert (which I do) or an EV certificate would be appropriate. Security has been a bit of nightmare with Excel addins. I've had to deal with false positives on and off again a bunch of times already. First it was windows smart screen, then antivirus vendors every so often. It's a slog...
Typically you can go into the file properties and check the “Unblock” checkbox to remove what Microsoft calls the “Mark of the Web”.
Open us a feedback through the app. We actually read every tiny bit.
Cool. How can I turn off the animated cursor movement in Excel? And Outlook? Drives me crazy. I keep submitting feedback. Even a registry hack is fine.
