Microsoft has confirmed a bug in Outlook Classic, where users are experiencing CPU usage spikes, as high as 50%, when simply typing in the application. Notably, reports of this incident can be traced back to November last year, and even now, users have been asked to switch to the Microsoft 365 Apps update channel as a temporary workaround.
After around six months since the first sighting, Microsoft is finally addressing an issue in Outlook (Classic), which led to increased CPU usage, visible slowdowns, and even freezes whenever you'd sit down to compose an email or type a message. Microsoft quotes a figure ranging from a 30-50% hit to the CPU utilization, and that's sure to be noticeable, especially on aging hardware.
