Fix Cannot Edit Working Hours in Project for the Web Calendar
Question details
Users are unable to modify working hours, days, or holidays in a calendar template or resource calendar.
- Product
- Microsoft Project for the web
- Device & OS
- not provided
- Scenario
- Attempting to edit a calendar template or resource calendar in Microsoft Project Plan 1.
- Observed behavior
- The screen flashes continuously and rejects or prevents any changes to the working days, hours, or holidays.
Ensure you have the necessary administrative permissions to edit calendar templates or resource calendars, and verify that your internet connection is stable before troubleshooting.
Perform Browser Troubleshooting and Verification
Determine if the issue is an isolated browser conflict by testing other environments and clearing your browsing data.
Since the screen flashing issue can occur across multiple browsers like Edge and Safari, isolating the environment is crucial. This helps determine whether the problem is a local browser cache issue or a backend service bug.
Open Microsoft Project for the web in a different supported browser (e.g., if you are using Safari, switch to Google Chrome or Microsoft Edge) to see if the calendar editing function works.
Navigate to your browser's settings menu, locate the privacy or history section, and clear your cache and cookies. Restart the browser and attempt to edit the working hours again.
If the issue persists, capture a short screen recording or take screenshots of the screen flashing when you attempt to change working days. Ensure no private or sensitive information is visible in the recording.
Report the Issue to Microsoft Support
If the calendar editing function remains unavailable across all browsers, escalate the issue to Microsoft for a backend resolution.
Manage Project Schedules and Calendars Offline with WPS Office
If Microsoft Project for the web is experiencing persistent browser bugs or server issues, consider managing your project schedules, working hours, and resources using WPS Spreadsheet. It provides a stable, offline-capable, and completely free alternative for your project planning needs.
- 1. Open WPS Spreadsheet: Launch WPS Office on your desktop and click on 'Spreadsheet' to start a new workspace.
- 2. Find a Project Template: Navigate to the 'Templates' section and search for 'Project Schedule' or 'Calendar' to access professionally designed, ready-to-use formats.
- 3. Customize Your Working Hours: Input your working days, resource hours, and holidays directly into the cells. You can save, edit, and update the file anytime without relying on web services.
Frequently Asked Questions
Why does the screen flash when editing calendars in Project for the web?
This is typically caused by browser rendering conflicts or a backend web service issue in Project Plan 1. Trying a different supported browser or clearing your cache can sometimes mitigate the flashing.
What information should I include when reporting this bug to Microsoft?
You should include your Project Plan details, the specific calendar type (template or resource), the exact browser versions you tested, and a short screen recording of the flashing behavior without exposing private data.
Do I need special permissions to edit a resource calendar in Project?
Yes, ensure you have the appropriate administrative or project manager permissions assigned in your Microsoft 365 account to modify calendar templates and resource working hours.
