How to send and schedule emails on behalf of another user in Outlook

Step 1: Add the other user’s mailbox

You only need to do this once.

1. Open new Outlook, or sign in to Outlook on the web.
2. In the left-hand folder list, right-click your own email address.
3. Select Add shared folder or mailbox.
4. Type the other user’s email address or name.
5. Click Add. Their mailbox appears at the bottom of your folder list.

Step 2: Choose who the email comes from

Always check the sender before you write, so the email goes out under the other user’s name.

1. Click New mail at the top left.
2. In the new message, open the Options tab.
3. Click From. A sender line now shows above your recipients and stays there for future emails.
4. Click the From line and select the other user’s email address.

Step 3: Schedule the send

Scheduled emails are sent from the cloud, so you can close Outlook or shut down your PC before the send time.

1. Finish your email: add recipients, a subject, your message and any attachments.
2. Do not click the blue Send button. Click the small arrow on its right.
3. Select Schedule send.
4. Choose one of the suggested times, or select Custom time to set an exact date and hour.
5. Click Send to confirm.

How to edit or cancel a scheduled email

1. Open your Drafts folder. Scheduled emails are kept here with a red [Scheduled] label.
2. Open the email and click Cancel send in the panel on the right.
3. The email reopens so you can edit it or schedule it again for a new time.
