How to send as an alias or shared mailbox in outlook.com

Before being able to send as, two settings must be changed on the admin portal:

To enable Send as Alias in the Microsoft 365 Admin Portal, follow these two steps:

Step 1: Enable “Send from Alias” in Exchange Online

  1. Go to Microsoft 365 Admin Center.
  2. Navigate to Settings → Org Settings.
  3. Click on Email.
  4. Look for “Send email from alias”, check the box, and click Save.

Step 2: Assign “Send As” Permission for the Alias

  1. In the Exchange Admin Center (https://admin.exchange.microsoft.com):
    • Go to Recipients → Mailboxes.
    • Select the mailbox where you want to send as an alias.
    • Click Mailbox Delegation (left panel).
    • Under Send As, click Add and select the user.
    • Click Save.

✅ Now, users can send emails using the alias in Outlook or OWA. It may take some time for changes to take effect.

Once that is done (sometimes as much as 10-15 minutes to wait for the delegation to take effect), then you can show the user how to send as that email:

If you need to send emails that do not require a response, you can set up a no-reply email account. Follow these steps to configure and use a no-reply email address:

  1. Ensure you are using Outlook.com for sending emails.
  2. Go to Settings.
  3. Select Mail.
  4. Click on Compose and reply.
  5. Check the box that says Always show from.

To send an email from the no-reply address:

  1. On the compose mail page, look for the From field above the To field.
  2. Type in the no-reply email address (e.g., no-reply@Canyonview.us) in the From field.
  3. Compose your email and send it.

Note: If recipients reply to the no-reply email, you will not see their responses, and neither will anyone else. Once you have sent an email from the no-reply account, you can easily select it in the From field for future emails without needing to type it in again.
