Question details
The user is unable to add team members or connect a project to a group because the member selection dialog appears completely empty.

- Product
- Microsoft Project for the Web
- Device & OS
- not provided
- Scenario
- Attempting to assign users to a project by opening the group member selector or the 'Connect your project to a group' dialog.
- Observed behavior
- The group member selector and group connection dialog boxes are completely blank, and restarting the application does not resolve the issue.
Ensure you have an active internet connection and the appropriate organizational permissions to view, create, or manage Microsoft 365 groups within your tenant.
Switch Browsers or Use Incognito Mode
Bypassing browser-specific caching errors and extension conflicts by accessing the application through a different supported web browser.
Often, browser cache, stored cookies, or conflicting browser extensions can cause popover dialogues in Microsoft web apps to render improperly.
While clearing the cache in the current browser is a standard step, switching entirely to a different browser frequently proves to be the most reliable and immediate solution.
Launch an alternative supported browser. For example, if the popover is blank in Microsoft Edge, open Google Chrome instead.
Navigate to Project for the Web and sign in to your Microsoft account.
Click on the group member selector or the 'Connect to a group' option to verify that the list now populates correctly.

Pre-Create the Group in Teams or SharePoint
Establishing the Microsoft 365 group in a different application first ensures it is fully synced and available to select in Project for the Web.
Manage Project Documentation Seamlessly with WPS Office
Browser-based project tools can sometimes slow you down with caching issues, blank popovers, or connection errors. For managing project tracking spreadsheets, reports, and presentations locally without browser dependencies, WPS Office offers a powerful, lightweight alternative to Microsoft Office.
- 1. Download the software: Visit the official WPS Office website and click the free download button.
- 2. Install WPS Office: Run the lightweight installer and follow the quick on-screen instructions to set up the suite.
- 3. Edit project files natively: Launch WPS Office to seamlessly view, manage, and edit all your project documentation and spreadsheets offline.

Frequently Asked Questions
Why is the Microsoft 365 group list empty even after I create one?
New groups created in Microsoft 365 or Azure Active Directory can sometimes take time to propagate across all services. Pre-creating the group via Microsoft Teams or SharePoint often forces a faster synchronization, making it visible in Project for the Web.
Will clearing my browser cache always fix the blank popover?
Not necessarily. While clearing the cache and cookies removes outdated browser data that might cause display issues, many users find that switching to a completely different browser, such as moving from Edge to Chrome, is a much faster and more reliable workaround.
Do I need special permissions to connect a project to a group?
Yes. To connect a project to a Microsoft 365 group, you must be the owner of that specific project and have the appropriate administrative permissions within your organization's tenant to create or manage groups.
