Outlook Freezing Issue for Microsoft 365 Users: Temporary Fixes and Solutions

Microsoft is currently addressing a significant issue impacting Microsoft 365 customers, where the classic version of Outlook experiences hangs or freezes when users attempt to copy text. This problem has been reported primarily on systems running Outlook Current Channel Version 2409 (Build 18025.20096) or higher, as well as on systems utilizing languages with an Input Method Editor (IME).

Overview of the Issue​

The affected users encounter a scenario where selecting text within a classic Outlook email and using the copy shortcut Ctrl+C results in Outlook becoming unresponsive. This disruption not only hampers productivity but also affects the overall user experience for those relying on Outlook as a primary communication tool within the Microsoft 365 suite.

Technical Details​

Microsoft has clarified that the issue surfaces specifically in the latest builds of Outlook Current Channel, version 2409 and above. Additionally, users operating Outlook in languages that require an IME are more susceptible to encountering this freezing problem. An IME facilitates the input of characters and symbols not readily available on a standard keyboard, which is essential for languages with complex scripts.

Microsoft's Response and Investigation​

Redmond has confirmed that the Outlook team is actively investigating the root cause of this newly identified issue. While a definitive fix is still in development, Microsoft has committed to providing updates and mitigation measures as they become available. The company is prioritizing this fix given the critical role Outlook plays in business communications and personal email management.

Temporary Workarounds​

In the interim, Microsoft has offered several temporary solutions to help affected users navigate around the problem:

1. Reverting to a Previous IME Version:
   • Steps to Revert IME:
     1. Open the Settings app on your Windows device.
     2. Use the search bar to find "IME settings."
     3. Select the IME settings for your chosen language.
     4. Click on General.
     5. Enable the "Use previous version of Microsoft IME" option.
   • This action downgrades the IME to a version that does not exhibit the freezing behavior, thereby restoring stability when copying text in Outlook.
2. Downgrading Outlook to a Previous Build:
   • Steps to Revert Outlook Build:
     1. Open Command Prompt by searching for it in the Windows search bar.
     2. Right-click the Command Prompt icon and select Run as administrator.
     3. Enter the commands provided by Microsoft to uninstall the current build and install a previous, stable version.
   • By reverting Outlook to an earlier build that predates the issue, users can continue using the application without interruptions.

Contextualizing with Recent Microsoft Updates​

This current issue is not an isolated incident. In September, Microsoft addressed another bug that caused Microsoft 365 applications, including Outlook, Word, Excel, and OneNote, to crash during typing or spell-checking operations. Moreover, one month prior, Microsoft introduced temporary fixes for issues that affected Gmail sign-in for classic Outlook users and caused Outlook to crash upon opening.
These recurring issues highlight the challenges faced by Microsoft in ensuring the stability and reliability of their software updates. However, the company has demonstrated a commitment to swiftly identifying and mitigating such problems to minimize user impact.

Impact on Users​

For businesses and individual users who rely heavily on Microsoft 365 and Outlook for daily operations, such disruptions can be particularly debilitating. In a corporate environment, the inability to copy text within emails can slow down communication, impede documentation processes, and frustrate users who depend on these tools for efficiency.
Moreover, the necessity to revert to previous software versions or adjust IME settings adds an additional layer of technical complexity, potentially requiring IT support intervention and further straining resources.

Looking Ahead: Microsoft's Commitment to Improvement​

Microsoft’s proactive stance in investigating and addressing these issues underscores their dedication to maintaining the integrity and performance of their software suite. While temporary fixes provide a short-term reprieve, the development of a permanent solution remains a priority to restore full functionality to Outlook.
Users are encouraged to stay updated through official Microsoft channels for the latest information on patches or updates that will resolve the freezing issue. In the meantime, adopting the recommended workarounds can help mitigate the inconvenience caused by this problem.

Best Practices for Affected Users​

To navigate this issue effectively, Microsoft advises the following best practices:

• Regularly Check for Updates: Ensure that your Microsoft 365 applications are up-to-date, as Microsoft frequently releases patches that address known issues.
• Backup Critical Data: Maintain regular backups of your emails and other crucial data to prevent potential data loss during application freezes.
• Seek IT Support if Necessary: For corporate users, involving the IT department can streamline the process of applying temporary fixes and managing software versions across the organization.

Conclusion​

The current Outlook freezing issue serves as a reminder of the complexities involved in maintaining large-scale software ecosystems like Microsoft 365. While disruptions can be frustrating, Microsoft's swift response and provision of temporary workarounds demonstrate their commitment to supporting users until a comprehensive fix is implemented. Users affected by this problem should apply the recommended workarounds and stay informed through official updates to ensure minimal disruption to their workflows.
