Fix Project Server PWA Filters and Groups Not Saving in Microsoft Edge
Question details
User needs to know why Project Web App (PWA) filters and groups stop saving after transitioning to Microsoft Edge, and how to fix it.
- Product
- Microsoft Project Server
- Device & OS
- not provided
- Scenario
- Migrating to Microsoft Edge from Internet Explorer while managing projects in Project Web App.
- Observed behavior
- Custom filters and groups created or modified in the Project Web App fail to save and persist across sessions.
Verify your user account permissions on the Project Server to ensure you have the appropriate access rights to save custom views, filters, and groups.
Enable Internet Explorer Mode in Microsoft Edge
Use Edge's built-in Internet Explorer compatibility mode to resolve legacy rendering and script execution issues common in older PWA versions.
Older versions of Project Web App rely heavily on legacy web technologies like ActiveX, which are not supported by the modern Microsoft Edge rendering engine. Enabling IE Mode bridges this compatibility gap.
Click the three-dot menu in the upper right corner of Microsoft Edge and select 'Settings'.
In the left sidebar, click on 'Default browser'.
Under 'Internet Explorer compatibility', find 'Allow sites to be reloaded in Internet Explorer mode (IE mode)' and select 'Allow' from the dropdown menu.
Click the 'Add' button next to 'Internet Explorer mode pages', paste the exact URL of your Project Web App, and click 'Add'.
Restart Microsoft Edge and navigate to your PWA site to test saving filters and groups.
Consult the Microsoft Project Community
Post your server configuration and issue details to official Microsoft support forums for specialized enterprise assistance.
Manage Projects Efficiently with WPS Office
While resolving complex Microsoft Project Server configuration issues can take time, your everyday office tasks do not have to wait. WPS Office offers a lightweight, completely free alternative for handling documents, spreadsheets, and presentations with high compatibility.
Frequently Asked Questions
Why does Microsoft Edge break older Project Web App features?
Microsoft Edge uses the modern Chromium engine, which intentionally omits support for legacy web technologies like ActiveX and VBScript. Older versions of PWA depend on these legacy technologies to save complex grid layouts, filters, and groups.
Can I fix PWA saving issues by clearing my browser cache?
Yes, occasionally corrupt cache data can interfere with background scripts. To rule this out, go to Edge Settings > Privacy, search, and services > Clear browsing data, and select 'Cookies and other site data' and 'Cached images and files' before trying again.
How do I verify if I have permission to save custom groups in PWA?
You need specific permissions assigned by your Project Server administrator. Contact your IT department to verify that your user account has the 'Save Custom Views' or equivalent administrative permission within the Project Web App.
