Voting buttons not present in received emails

Scenario

You are using Exclaimer Cloud, and you notice that the voting buttons are not present in received email messages.

Reason

Voting functionality is stored in a TNEF MAPI property. When an email message is routed via a send connector, it undergoes content conversion to Multipurpose Internet Mail Extensions (MIME). However, the MIME format does not preserve the TNEF MAPI property, so voting buttons are not displayed.

Resolution

To resolve this issue - please click on the required options listed below to go through the detailed description:

Enable the Transport Neutral Encapsulation Format (TNEF) for Microsoft 365
  1. Connect to your Microsoft 365 environment (for instructions, see Technet website - Connect to Exchange Online PowerShell).

  2. Run the following Powershell command: 
    Get-RemoteDomain | fl
  3. A list of attributes is displayed. Locate TNEFEnabled - it should be blank:

  4. Type the following command: 
    Set-RemoteDomain * -TNEFEnabled $true

    This will return with no results, as below:

  5. Type the following command:
    Get-RemoteDomain | fl
  6. You will see TNEFEnabled is set to True:

In a hybrid environment, enable the Transport Neutral Encapsulation Format (TNEF) for Exchange as well
To enable the TNEF for Exchange, follow the same process as described above, with one slight difference.

In Exchange, you will have multiple Remote Domains, so make sure you make the change to the correct one.

  1. In the command prompt, type the following: 
    Get-RemoteDomain

    You will see multiple domains; for example:

  2. Change the Domain name that has a .mail.onmicrosoft.com suffix.
    In this example, we're using exclaimerqatest.mail.onmicrosoft.com (please ensure you use the name, not the domain name).

    Type the following command:
    Get-RemoteDomain "hybrid domain - Exclaimerqatest.mail.onmicrosoft.com" | fl
  3. A list of attributes is displayed. Locate TNEFEnabled - it should be blank:
    img5.png

  4. Type the following command:
    set-RemoteDomain "hybrid domain - Exclaimerqatest.mail.onmicrosoft.com" -TNEFEnabled $true
  5. You will see TNEFEnabled is set to True:

Once this procedure has been followed the Voting buttons will work.
