Summary
Microsoft is investigating a bug in the classic Outlook desktop client that causes the mouse pointer to disappear for some users. While not explicitly a security vulnerability, usability issues can sometimes lead to security compromises.
IFF Assessment
FRIEND
Microsoft is actively investigating and presumably working to fix the bug, which is good for users.
Defender Context
While a disappearing mouse pointer is primarily a usability issue, it can frustrate users and potentially lead them to bypass security measures in their attempts to resolve the problem. Defenders should be aware of the issue and guide users to official Microsoft recommendations for mitigation, avoiding potentially malicious workarounds suggested elsewhere online.
