How email aliases work with CodeTwo email signatures in Microsoft 365


You would like to know how signatures are added to email aliases by CodeTwo Email Signatures 365.


CodeTwo Email Signatures 365 supports adding both cloud (server-side) and Outlook (client-side) signatures to email aliases. The list below contains the most frequently asked questions about how CodeTwo Email Signatures 365 supports email aliases.

  1. When I send an email from an email alias, what contact information will appear in my email signature?
    In the case of Outlook (client-side) email signatures, it depends on which CodeTwo Outlook add-in you use. If you’ve deployed the modern Web Add-in, an Outlook email signature will contain the contact details of the user who sends the email in Outlook for Windows, Outlook for Mac or Outlook on the web (OWA). The details will be the same as for that user’s primary email address. For the legacy COM Add-in, the signature will include the details of the user who is signed in to the add-in.

    Cloud (server-side) email signatures will contain the contact details of the user who sends the email (the primary email address). So it does not matter if you send using your email alias or your main email address - the signature is always the same. For example, if you use the {E-mail} placeholder in your template, it will show the primary email address of the user who sends the email (not the alias email address). This is because placeholders are filled with values from your Azure Active Directory, and these values are always defined for the primary SMTP email address.
  2. Are aliases licensed separately?
    No, aliases don’t consume their own licenses. Licenses are consumed on a per-user basis and it doesn’t matter how many aliases are used to send emails by a given user - only one license will be consumed by this user.
  3. When a licensed user sends an email from an alias, which address will appear in the licensing information in CodeTwo Admin Panel?
    CodeTwo Admin Panel does not display aliases, but only primary email addresses of the users whose emails are routed through the CodeTwo cloud service. You can check the currently licensed users by following steps in the user's manual.
  4. Can aliases be added to conditions or exceptions of an email signature rule?
    Not at the moment, but this feature is on our roadmap.
