The fastest way to assign a task in Outlook
To assign a task in Outlook, open the Tasks module, select New Task, fill in the subject and details, then click the Assign Task button. A dialog box appears where you enter the recipient's email address. Click Send, and Outlook sends them a task request they can accept or decline.
The person you assign the task to receives an email notification. Once they accept, the task appears on their task list and you can track its status. If they decline, you get a notification and the task returns to your list.
This works the same way in Outlook on the web, Outlook desktop for Windows, and Outlook for Mac, though the button locations vary slightly depending on your version.
Key Takeaways
- Assigned tasks send an email to the recipient, who must accept or decline before the task moves to their list.
- You can only assign a task to one person at a time — Outlook does not support assigning to multiple recipients in a single request.
- The recipient's response (accepted or declined) generates a notification back to you, so you know whether they took on the task.
- Assigned tasks can include a due date, priority level, and description to give the recipient full context about what you need done.
Step-by-step: Assigning a task in Outlook desktop
Open Outlook and navigate to the Tasks module by clicking the Tasks icon in the left sidebar, or press Ctrl + 4 on Windows or Cmd + 4 on Mac. If you do not see a Tasks icon, click More (the three dots) at the bottom of the sidebar and select Tasks from the menu.
Click New Task at the top of the window. A task creation form opens. Enter a subject line that clearly describes what needs to be done — for example, "Review Q4 budget report" or "Update client contact list." Add a description in the body field if you want to provide more detail or context.
Set the due date by clicking the Due Date field and selecting a date from the calendar. You can also set a Start Date if the task should not begin immediately. Use the Priority dropdown to mark the task as High, Normal, or Low.
Click the Assign Task button. A dialog box appears with a field for the recipient's name or email address. Type the person's email or select them from your contacts. Click Send. Outlook sends the task request to their inbox as an email notification.
Assigning a task in Outlook on the web
Log into Outlook on the web and click the Tasks icon in the left sidebar. If you do not see it, click App launcher (the grid icon) in the top left and select Tasks from the menu.
Click New Task or the plus icon. Enter the task subject and any details you want to include. Click Assign (or Add Assignee depending on your version). A field appears where you type the recipient's email address or name. Select them from the dropdown that appears.
Set the due date and priority, then click Save or Send. The task request goes to the recipient's inbox. They will see it as an email with options to accept or decline.
What happens after you send a task assignment
The recipient receives an email with the task details and two buttons: Accept and Decline. If they click Accept, the task moves to their task list and you receive a notification that they accepted it. The task now appears in both your list (marked as assigned) and theirs (marked as accepted).
If they click Decline, the task returns to your list and you get a notification that they declined it. You can then reassign it to someone else, modify it, or handle it yourself.
You can check the status of an assigned task by opening it in your task list. The status field shows whether it is pending (waiting for their response), accepted, or declined. You can also see the due date and any updates the recipient has made to the task description.
Assigning a task to yourself from an email
You can create a task directly from an email message without opening the Tasks module. Right-click an email and select Follow Up or Create Task (the exact wording depends on your Outlook version). A quick task creation window appears with the email subject pre-filled.
Add a due date and any additional details, then click Save. This creates a task in your list linked to that email. However, this method creates a task for yourself only — to assign it to someone else, you must open the task afterward and click Assign Task.
Limitations and things to know
Outlook only allows you to assign a task to one person at a time. If you need the same task done by multiple people, you must create separate task requests for each recipient. There is no way to assign a single task to a group or distribution list.
The recipient must have an Outlook or Microsoft 365 account to receive and respond to task assignments. If you try to assign a task to someone using a different email system, they may receive the notification as a regular email but will not be able to accept or decline it through Outlook.
Assigned tasks do not sync across all devices the same way regular tasks do. If you assign a task on desktop and then check Outlook on your phone, the assignment status may not update immediately. Refresh your task list or wait a few minutes for the status to sync.
Frequently Asked Questions
Can I assign a task to multiple people at once?
No. Outlook only allows one recipient per task assignment. To assign the same task to multiple people, create separate task requests for each person. Each recipient gets their own copy of the task and can accept or decline independently.
What if the person I assigned the task to does not respond?
If they do not accept or decline within a few days, the task remains in a pending state on your list. You can send them a reminder by opening the task and clicking Resend, or you can reassign it to someone else. There is no automatic timeout or expiration.
Can I change a task after I have assigned it?
Yes. Open the task in your list and edit the subject, due date, description, or priority. If the recipient has already accepted it, they will see the updated version. If they have not responded yet, they will see the changes when they open the assignment notification.
What is the difference between assigning a task and sharing a task list?
Assigning a task sends a one-time request to a specific person for a specific job. Sharing a task list gives someone ongoing access to view and edit all tasks in that list. Use task assignment for individual requests and task list sharing for ongoing collaboration.
Does the recipient need Outlook to accept an assigned task?
They need a Microsoft 365 account or Outlook.com account to accept through Outlook. If they use a different email system, they will receive the notification as an email but cannot formally accept or decline it in Outlook. You can still track it manually by asking them to confirm.
