Each mailbox has its Primary email address (UPN) and alias email addresses that can be used to receive mail, but not to send from. Your alias may vary from the Primary email address in the username part or domain name part. Read the Knowledge Base article on What Are Email Aliases for an Exchange Mailbox? for more information.

Important: It is impossible to send messages from the mailbox alias. This article describes a workaround on how to send from your alias email address. To do that the alias must be converted into a Distribution List. Follow the instructions below for each user you need to be able to send from alias email address.

  1. Log in to HostPilotĀ® Control Panel and navigate to Users & Services > Exchange Mailboxes.
  2. Click Action next to the user in question and select Edit Email addresses:

    Edit email aliases

  3. Remove the email address you want to send as, from the list of aliases and wait a couple of minutes:

    Remove address from aliases

  4. Navigate to Users & Services > Distribution Lists and click Create New Distribution List.
  5. Specify the name and assign to this new Distribution list the previously deleted email address (former alias you want to send from):

    Create DL with alias email

    If the error stating that the email address is already registered appears, it means that the alias has not yet been removed completely from our system. Try again in 5 minutes.

    Error: email already registered

  6. Add the user in question as a member of this distribution list:

    Add user to DL

  7. Grant Send As permissions to the distribution list following instructions in this Knowledge Base article How To Send Emails As A Distribution List and wait for propagation time. In order for permissions to work properly, Distribution List should not be hidden from the Global Address List.

    Note: Send As Distribution List permissions can be only granted to Exchange mailboxes.

You can now send from this address using Outlook or OWA (https://exchange.intermedia.net/ControlPanel/Login?ClientType=WebMail).

In Outlook:

  1. Compose a New Email. Click the From field and select Other email address.

    Note: If you do not see the From field, navigate to Options and select From in the section Show fields.

    Show From

  2. Select the alias from the Global Address List or type the email address manually.

    Enter DL's email in From Field

  3. Send the email from your alias.
