[Planner App] - Unable to load roster when user deleted from organization

Question

II have an internal business app that creates Planners for long duration customer projects. The duration of these engagements means that it is highly likely that an employee at our organization will leave the company at which point our IT staff deletes them from Microsoft Entra. This is causing the Planner App in Teams to show the following banner message when users access a Planner with the deleted user

This is also preventing the users from being able to assign users to a task or to view the current member list through the Share Button.

Using the Graph APIs, the call to retrieve the roster members is not erroring, but it still contains the now deleted user(s) so that (presumably) when MS teams calls the Graph APIs to resolve a users info the individual user APIs returns a 404 error which is causing this issue. As far as I know, we are on the Basic plan so based on https://learn.microsoft.com/en-us/planner/delete-user-data the deleted users should be getting marked as "Former Employees" but it seems this may be dependent on how the user gets removed from the organization

Hi @Justice, Elliot

According to your case description, when accessing Planner with a deleted user, this will cause the Planner application in Teams to display the banner message we couldn't load the users for this plan.

This issue may be caused by the deleted user still being referenced in the plan, causing Planner to be unable to load the user information. Please try the following possible solutions:

• Manually update plan members: Make sure there are no deleted users in the plan. Open Microsoft Planner and select the plan that needs to be updated. In the upper right corner of the page, select the Members icon. Find and delete the user of the former employee and click the X next to the user to remove it.
• Clear cache: Try clearing the cache of your browser or Teams application and then reload Planner.
• Check the deletion status of users in Microsoft Entra: Sign in to the Microsoft Entra admin center with administrator credentials. Go to Identity > Users > Deleted users. Here, you can see a list of users that have been deleted in the past 30 days. It may take a while for it to sync with Teams, so please be patient.
