Hello Amanda, thank you for reaching out to the Microsoft Q&A forum.
From this point forward, I’ll be taking over from Austin to assist you directly in this thread, and I apologize for any inconvenience caused.
Based on your description and my research, this behavior is expected with Microsoft 365 / Exchange. Outlook and Exchange typically resolve the sender display name to the default display name of the mailbox that actually sends the message, and they do not reliably honor a dynamically set “From” display name on a per‑message basis.
This behavior has been reported for many years and still applies in many scenarios, as discussed here: Display sender name as set in message header, instead of full name from address book

In my own testing using WordPress with FluentSMTP via the Microsoft (Outlook/Office 365) API connection, I observed the same behavior described in that thread. Even after changing the sender name in the message configuration, the Outlook inbox continued to show the display name configured on the Microsoft 365 sending account, rather than the custom name.
While I don’t currently have Divi available to test the exact contact form behavior, your symptoms align closely with what we typically see with Microsoft 365 / Exchange. In this case, the solution is more workaround‑based, as there is no reliable setting to force Outlook to display a different sender name per message.
- Update the Divi contact form Subject to include the submitter’s name (and optionally company/email), for example:
Contact form - {Name} - {Company}This makes the messages easy to identify in the message list and easy to filter/search with Outlook rules. - Turn on Message Preview in Classic Outlook so the first line(s) of the email body appear in the list view (handy if your email body starts with “Name: …”). You can do this from View > Message Preview and choose how many lines to show.
I hope this helps clarify the behavior you’re seeing. If you have any additional questions, please don’t hesitate to ask.
