The Outlook mouse bug is causing major frustration for users of the classic Outlook desktop application, as Microsoft has acknowledged the issue of the mouse pointer disappearing. This acknowledgment comes nearly two months after initial reports surfaced online, highlighting how the Outlook mouse bug renders the application almost unusable for some.
Users have reported that the mouse pointer vanishes while using Outlook, severely impacting their ability to navigate, open emails, and perform basic tasks like copy and paste. Microsoft is now actively investigating the Outlook mouse bug.
Microsoft Investigates the Outlook Mouse Bug
Microsoft has detailed the issue in a recent support document, explaining that the mouse pointer or cursor disappears as users move it across the Outlook interface. This Outlook mouse bug isn’t limited to Outlook, as some users of other Microsoft 365 apps have also reported similar issues, though to a lesser extent.
“When using classic Outlook, you may find that the mouse pointer or mouse cursor disappears as you move the pointer over the Outlook interface,” Microsoft stated.
The Outlook team is working to understand the underlying cause and will provide updates as they become available. Microsoft is urging affected users to contact their Microsoft 365 administrator to open a support case with the Outlook Support Team and submit diagnostic log files to aid in the investigation. While a permanent fix is in development, Microsoft has offered temporary workarounds.
Temporary Workarounds for the Missing Mouse Pointer
While a definitive solution is being developed, Microsoft suggests a few temporary fixes. One workaround involves clicking an email in the message list when the cursor disappears, which may cause it to reappear. Alternatively, switching to PowerPoint, clicking into an editable area, and then returning to Outlook might also restore the mouse pointer. If these steps fail, restarting the computer is recommended as a temporary solution.
These workarounds provide some relief, but they are not ideal for long-term productivity. Users are eagerly awaiting a permanent fix from Microsoft to resolve the disruptive Outlook mouse bug.
Recent Fixes and Ongoing Issues
Last month, Microsoft addressed another issue in classic Outlook that prevented Microsoft 365 customers from opening encrypted emails after installing the December 2025 updates. You can find more related Fraudulents news on our website.
