The administration and maintenance of Microsoft Exchange Server to ensure secure, reliable, and efficient email and collaboration services across an organization.
Thank you for sharing your concerns.
First, I’d like to clarify that this is a user‑to‑user support forum. Moderators participating here do not have access to backend systems, nor can we directly intervene in Microsoft product functionality. Our role is limited to providing technical guidance and sharing best‑practice recommendations based on reported issues, requests, and scenarios.
Currently, I have not identified any official Microsoft documentation or related community threads confirming that Outlook on the web (OWA) in Exchange Server 2019/SE provides a dedicated “Forward email as attachment” option comparable to what is available in Exchange Online.
This function may vary depending on factors such as the specific OWA version, cumulative update (CU) level, browser used, or overall environment configuration. In some scenarios, the functionality may exist but is not exposed as a direct or explicit action within the OWA user interface.
To help you reach your goal more effectively, I recommend engaging with [GitHub Community Forum] for a deeper technical dive or to connect with individuals who have relevant experience and expertise. Some approaches may behave differently or be restricted depending on your specific environment and configuration. These forums include many experienced developers and Microsoft specialists who can assist with troubleshooting and guidance.
If you have any additional concerns, feel free to comment below. I would be more than happy to assist.
