How to Fix Microsoft 365 Apps Crashing at the Same Time Every Day
Question details
The user needs to resolve an issue where multiple Microsoft Office applications crash simultaneously at a fixed time daily.
- Product
- Microsoft 365
- Device & OS
- Windows
- Scenario
- Using multiple Microsoft Office applications in a local Windows setup or a Windows 365 remote desktop environment.
- Observed behavior
- Word, Outlook, Excel, PowerPoint, and other Microsoft applications unexpectedly crash at the exact same time every day.
Before proceeding with system changes, save all active documents and note the exact time the crashes occur to help verify if the troubleshooting steps are successful.
Create and Test a New Windows User Account
Testing with a fresh user profile helps determine if the daily crashes are caused by local profile corruption.
A corrupted local Windows user profile can trigger scheduled errors that cause applications to close unexpectedly. Creating a new local administrator account provides a clean environment to isolate the problem.
Press the Windows key + I on your keyboard to open the Settings application, then click on Accounts.
Navigate to 'Family & other users' (or 'Other users' depending on your Windows version), click 'Add account', and follow the on-screen prompts to set up a new local administrator account.
Log out of your current session and sign into the newly created Windows account. Open your Microsoft 365 apps and wait through the specific time the crash usually occurs.
Contact Your Microsoft 365 Administrator
If the issue persists on a new user profile, it indicates a backend issue with the Windows 365 remote desktop environment that requires administrative support.
Switch to WPS Office to Avoid Daily Crashes
If Microsoft 365 continues to crash and disrupt your daily workflow due to persistent profile or backend remote desktop issues, consider switching to WPS Office. It provides a stable, independent desktop environment without relying on complex remote infrastructures.
- 1. Download the software: Visit the official WPS Office website and click the free download button for Windows.
- 2. Install WPS Office: Run the downloaded setup file and follow the standard installation wizard.
- 3. Open your existing files: Launch WPS Office and directly open your Microsoft Word, Excel, and PowerPoint files to resume your work without interruptions.
Frequently Asked Questions
Why do my Microsoft Office apps crash at the exact same time every day?
Simultaneous daily crashes are typically caused by scheduled background tasks conflicting with a corrupted Windows user profile, or automated maintenance and synchronization issues within a Windows 365 remote desktop environment.
Will reinstalling Microsoft 365 fix apps crashing at a scheduled time?
If the crashes are caused by a corrupted user profile or a backend Windows 365 remote environment issue, simply reinstalling the software usually will not resolve the problem. Creating a new local user account is the recommended first step.
How do I know if the crash is caused by my Windows user profile?
By creating a new local Windows account and leaving the Office apps open on that new profile. If the applications do not crash at the usual time, your original user profile is corrupted and causing the issue.
Can third-party add-ins cause Microsoft 365 apps to crash simultaneously?
While add-ins can cause general instability in individual applications, crashes that happen at the exact same time every day across multiple different apps (like Word and Excel simultaneously) are almost always related to system-level scheduled events or remote desktop environment issues.
