In recent months, the company also addressed a slew of other Microsoft 365 and Office issues, including a widespread licensing issue blocking access to Microsoft 365 services for some customers with Family subscriptions and a bug triggering Outlook crashes when clicking a button that should've helped users switch back to classic Outlook. In a new support document published this week, Microsoft now revealed that this known issue can impact those in the Current Channel, Monthly Enterprise Channel, or Insider channels updated to Outlook Version 2406 Build 17726.20126 and later. Microsoft warned Windows users of increased CPU usage when typing while using recent versions of the classic Outlook email client. Previously, it fixed a known issue that broke Outlook email drag-and-drop after installing recent updates on Windows 24H2 systems and another bug that caused Outlook to crash when writing, replying to, or forwarding emails. Last week, Microsoft also released emergency Office 2016 updates to fix crashes in Word, Excel, and Outlook after installing the April 2025 security updates. While Redmond's engineers investigate, the company advises affected Outlook users to switch to the Semi-Annual Channel, unaffected by these CPU spikes, until a solution is available. IT admins can also switch channels for devices in their organizations using Group Policies, the Office Deployment Tool, Microsoft Configuration Manager, Intune, the Microsoft 365 Apps admin center, or the Microsoft 365 admin center.
