How to disable html format in OWA

Hi Folks, 

 

Is there a way we can disable HTML formatting in OWA organization wide?

 

We can make changes per users basis on https://outlook.office.com/mail/options/mail/messageContent but we rather like a way to disable the HTML emails for everyone in the organization - I looked up for a related attribute in OrgConfig/remote domain and OWAMailboxPolicy but found nothing related. 

 

Any help would be appreciated.

    You can toggle this on/off via PowerShell, so it's easy to automate across multiple users:

     

    Set-MailboxMessageConfiguration user -DefaultFormat PlainText

     

    Note that this setting only applies to OWA.

      This indeed helps us but we wanted a way to disable HTML formatted emails both incoming and outgoing. Is there a way this can be achieved?

        Hi TechAB,

         

        in other words you wish to convert all ingoing emails from HTML to  the plain text. correct?

        If so you have to create a custom transport agent (if you are running on-premise Exchange server).
