Question details

Users need to know how to assign the same resource to multiple tasks simultaneously in Microsoft Project, particularly addressing limitations found in Project for the web.

Product: Microsoft Project
Device & OS: not provided
Scenario: Assigning team members or resources to several project tasks at once to save time and streamline project management.
Observed behavior: Project for the web forces users to assign resources one task at a time and does not support bulk assignment, whereas the desktop version provides this capability.

Before you start

Before assigning resources in bulk, verify your team's availability and working hours in the project settings to prevent accidental resource overallocation.

Solution 1Recommended

Bulk Assign Resources in Microsoft Project Desktop

Use the desktop version of Microsoft Project to assign one resource to multiple tasks at the same time efficiently.

Select multiple tasks

Hold down the Ctrl key (or Shift key for adjacent tasks) and click on the specific tasks you want to assign the resource to in your task list.

Open the Resources tab

Navigate to the top ribbon menu and click on the 'Resources' tab to view resource management options.

Assign the resource

Click on 'Assign Resources'. In the dialog box that appears, select the desired resource from your list and click the 'Assign' button.

Check for Overallocation: After bulk assigning, review the Resource Sheet to verify if the newly assigned resource is overallocated, and adjust their working hours or task timelines if necessary.

Solution 2

Assigning Resources in Project for the Web

Since bulk assignment is not supported in the web version, resources must be assigned to each task individually.

Frequently Asked Questions

Why can't I bulk assign resources in Project for the web?

Microsoft Project for the web is a streamlined, lightweight version of the desktop application. It currently lacks some of the advanced features found in the desktop version, including bulk resource assignment. Users must assign resources to each task individually.

How do I know if a resource is overallocated after bulk assignment?

In Microsoft Project desktop, an overallocated resource will typically be highlighted in red in the Resource Sheet. Additionally, a red warning icon indicating overallocation will appear in the indicator column next to the affected tasks.

Can I copy and paste resource assignments in Project for the web?

No, directly copying and pasting resource assignments across multiple tasks is not supported in the web version. Each task's resource must be updated individually via the 'Assign to' column.

Do I need a specific license to use the desktop version of Microsoft Project?

Yes, accessing the desktop version of Microsoft Project requires a qualifying Project Plan 3 or Project Plan 5 subscription, or a standalone perpetual license such as Project Standard or Project Professional.
