How to have an Office 365 email signature inserted only into new emails?

Do your email signatures pile up at the bottom of your conversation threads? Well, I have the bad news and the good news for you. The bad news is that this is the default setup for Office 365 email signatures. The mail flow rule can insert email signatures at the very top or the very bottom of the whole email thread. The good news is that there are ways to work around it. Let’s get right into this.

Office 365 native solution

To solve the problem natively, you have to add email signatures to new messages only. Follow the steps below to see how to do it:

  1.  Log in to the Office 365 portal by using your Exchange Online admin account.
  2.  Click the Admin app and then select Exchange to open Exchange admin center.
  3. Then, click mail flow > rules and create a new rule by clicking the plus (+) icon. The new rule wizard will pop up.
  4. Name the rule, and click More options at the bottom of the window.
  5. Set conditions that have to be met by the message for the rule (signature) to be initiated.
  6. Now, set up an action in the Do the following section. Hover over the Apply a disclaimer to the message and then append a disclaimer.
  7. To open the email signature editor, click Enter text on the right. Here you can compose your email signature template. Office 365 supports the HTML format only. To make it easier, you can use templates from free email signature generator or Templates library.
  8. To set an action for the rule to undertake in case the disclaimer can’t be inserted (e.g if a sent message is encrypted) , click Select one… .
  9. Next, hover over the Except if… and continue with the subject and the body and then subject and the body matches these text patterns. Click Enter text patterns and insert a copied piece of your disclaimer code into the text bar. Click OK to save.

With this mail flow rule, only new messages in an email thread will get the signature. This i a native solution allowing you to prevent signatures from piling up at the bottom of the email conversation.

Limitations of native Office 365 email signatures

Native email signatures come with some limitations:

  • The rules are managed on the server level and can only be implemented in Office 365.
  • You won’t be able to place your signatures under the latest reply.
  • There’s no HTML signature editor.
  • No way to remove blank spaces after empty Active Directory fields.
  • Forcing email format is not available.

As Office 365 is unable to divide a message chain into units, all embedded signatures pile up at the bottom of an email thread instead of being added right under every response. Not only is it unaesthetic but also makes using email signatures kind of pointless. If you plan to get more control over Office 365 email signatures, then you should consider a third-party solution.

  1. PD

    method 1 doesnt work – sig is still applied multiple times for me. Have tried multiple times, tried using the full sig as the comparison text, just part of the sig, tried saving it, closing outlook , reopening waiting etc . Still appends multiple times.
    Crazy MS doesnt fixed this basic functionality.

      Hi Phil,
      Try using “subject or body includes any of these words” and enter the fragment of a disclaimer then.
