Microsoft has revealed ActiveX will be disabled by default in Microsoft 365 starting this month, citing security as the company’s key deciding factor.

Microsoft 365 is now complete: ActiveX is being turned off ActiveX follows Flash. The risky plug-ins will soon no longer work by default in Microsoft 365 apps.

It's been quiet for a while, but ActiveX is still around. Upcoming Microsoft Office versions will finally switch off support. At least almost.

The updates will include a fix for a widely reported vulnerability in Microsoft Word, as well as changes to the way Internet Explorer (IE) handles ActiveX that might cause headaches for some.

In Microsoft’s latest security updates on Tuesday, the software vendor also released a “kill bit” for the affected ActiveX control to block it from running within IE.
