@chico and @Anonymous Would you be able to share a screenshot of what your flows look like? This is the first I have heard that you can do the "run as" option. And I would like to see how you add an approval option to the "send email". Thank you!
when sending an email with options, the default is that it will send from the owners account. The owner of the Flow... So its not really a solution to the orginal issue that started this thread...
But for other times when you have no issue sending an email from the owner of the Flow,
Adding the Requested by field does nothing about the actual FROM-SENDER: which is Microsoft Flow <maccount@microsoft.com>
Folks have been asking for a simple FROM field to address this for quite some time.
It seems like approvals should have this by default as it is a very basic and necessary item.
These are typically apps and emails internal to each of our organizations and the MS account will always appear as a Caution - EXTERNAL EMAIL warning in outlook.
You can now customize who the Approval appears from - read more here: https://flow.microsoft.com/blog/button-types-more/
