Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Good day! Welcome to Q&A forum!
Thank you for contacting us regarding the issues you're experiencing with your Microsoft 365 applications after updating your iPhone to iOS 26 Public Beta.
I want to acknowledge that this situation is a common occurrence with pre-release operating system software like iOS 26 Public Beta. Here's what you can do from your side, and important information regarding a resolution:
Ensure Microsoft 365 Apps are Updated: Please check the App Store on your iPhone for any available updates for your Microsoft 365 applications (Word, Excel, PowerPoint, Outlook, Teams, OneDrive, etc.).
Perform Basic Troubleshooting Steps
- Force Close and Restart Apps
- Restart Your iPhone
- Reinstall Apps
Report the Issue to Apple: It is crucial to report these compatibility issues directly to Apple on your iPhone. Providing detailed reports (e.g., which app crashes, exact steps to reproduce, any error messages) helps Apple identify and rectify bugs within the iOS 26 Beta itself. This collaboration between app developers and Apple is key to stabilizing the beta.
As a general guideline, beta operating systems are not recommended for primary devices or for use with critical business applications. Their purpose is for testing new features and identifying bugs before a stable public release. Issues with application compatibility are an expected part of the beta testing cycle.
If the disruption to your workflow is significantly impacting your business operations and the basic troubleshooting steps do not provide sufficient relief, the most reliable way to restore full functionality to your Microsoft 365 apps is to downgrade your iPhone back to the latest stable public version of iOS (currently iOS 18.5).
Please be aware that downgrading typically involves erasing your device and restoring from a backup made before you installed the iOS 26 Beta. If you proceed with this, ensure you have a suitable backup to prevent data loss. Instructions for downgrading can be found on Apple's developer support pages.
Thank you for your patience and understanding. Please stay updated for any news of the official release of IOS 26. Please let me know if there are any other concerns.
