How email aliases work with CodeTwo email signatures in Microsoft 365

Problem:

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

Solution:

CodeTwo Email Signatures for Office 365 supports adding signatures to email aliases in both server-side and client-side signatures. The list below contains the most frequently asked questions about how CodeTwo Email Signatures for Office 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 client-side email signatures, it depends on which CodeTwo Outlook add-in you use. If you’ve deployed the modern Web Add-in, a client-side email signature will contain the contact details of the user who is signed in to their Microsoft 365 account in Outlook for Windows, Outlook for Mac or OWA. For the classic COM Add-in, the signature will include the details of the user who is signed in to the add-in.
   
   Server-side email signatures will contain the contact details of the user (the primary email address) who sends the email. 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 the 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 Email Azure 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.
