How to add different signatures to users belonging to different domains


You use several domains in your Microsoft 365 (Office 365) tenant and want different signatures to be added to users in each domain.


The quickest way to have CodeTwo Email Signatures 365 add different signatures to users located in different domains is to set up a separate rule for each domain in the signature management app. Each rule will contain information on the domain and will add a signature only to users that belong to the domain specified in that rule.


You have two domains: and Users A and B are in the domain; Users C and D use the domain. You want users C and D to have a different signature than users A and B.

  1. Sign in to and create a new signature rule - either cloud (server-side) or Outlook (client-side).
  2. In the Senders step, click the Add button and choose Azure AD filter (Fig. 1.).
