DFSS Send email – deprecated soon?

[Jon Whisman]

Hi – found some articles below and was curious if the DFFS Send email capability will be impacted by all of the upcoming Microsoft retirements / End of Life chamges coming in 2026.

We are preparing many of out sites and workflows for possible retirement next year in oue enterprise and wondering about the long-term impact if we continue to use DFFS send email vs. workflows to send emails.

Hi,
I’m aware of this deprecation and will have other options available in time.

It will basically mean that emails configured in the DFFS configuration will be sent by the logged in user and not the “system account” like today.

An alternative will be to write the email to a custom list where a Power Automate FLOW can be created to pick up and send the email.

A third option that I might add support for is to use “send on behalf of”, but for this to work all users would have to be granted “send on behalf of” permissions for a “service account” that is used to send the emails.

Not sure if the third option will be something that a typical IT-department would allow – what do you think?
