Changing Email Sender address

I have added multiple accounts under connections of a request triggered flow. It sends emails. The sender is currently being picked from the request body but it gives unauthorized error unless it is the default one.

Re: Changing Email Sender address

Hi @taharaza,

 

The reason for the error message should be caused by the Mail service.

Under Microsoft Flow, the Mail connection is using the corresponding user credentials to operate with the Mail service, if we would like to change the From field, it would require Flow to change authentication information within the connection, which is not supported.

Further, the reason for the error message means the information under the From field is transfered to the Mail server, but the server refused the request, because if you would like to send the Email with another account based on the current user credential, it would require special permission configured for the related MailBox.

See reference: Give mailbox permissions to another user in Office 365 -Admin help

 

Also, another thread for your reference:

Changing Sent From Default Address
