Send on Behalf of O365 group for Send Email Action

Hi, wonder if anyone has any ideas on this...  I'm building flows for a large organisation.  The email notifications come from my own email address so I've created an O365 group for my team and now using the associated email address.  I've handed the flow to the business user and they say when they manually test the flow that emails aren't being received.  They don't receive an error, so I assume when the Flow is run under their account, they are not permitted to send from the group email address.  Therefore, I am considering building a public Group -   This will likely solve the situation.. Just wondering if anyone has tried this.  Thank you!

Hi @Brice235i ,

Sending an email from a group email address is not supported in microsoft flow currently, 

I afraid that there is no way to achieve your needs in Microsoft Flow currently.

There is a similar idea you can vote with:

Sorry, don't understand.  This functionality is already provided.. It is in the advanced settings of the Send Email action. Just wondering whether to create a public O365 group and use the shared mailbox of this group, or create a traditional Shared Mailbox in Outlook and ensure the delegates have "Send As" or "Send on Behalf of" priviledges.  See screenshot attached.Capture.PNG


I do not see the 'send as' in flow.

Is this instance specific?

Did you got it working?

"Form (Send As) is now in V2 Send Email Action!  It wasn't at first.

Send as only works from a Shared Mailbox and not from an O365 Group mailbox. You need access rights to send mails from the Shared Mailbox too, otherwise it will fail.

Hi @CologneClaret,

your statement is wrong. My test shows that you can send as Office 365 group.

Have a look at this:
