Getting One or more recipients are invalid error

I am trying to send an email to the Shared mailbox. It is hard coded in the flow but when I try to send an email, it gives the 

One or more recipients are invalid error.
I am able to send email to that shared mailbox using my outlook client but not using power automate.
I tried with SP.Utility and Send Email Outlook actions and in both of them the same error is occurring.
Can anyone help here to identify what is going wrong?

Hi @dhruvp29 ,

possible issue:

1) I believe the issue is with the email address.

check the email address is correct in the power automate flow.

2) check if power automate user has access to full access to the shared inbox.


hope so this helps

I had the same error. "One or more recipients are invalid. clientRequestId:...... "

My error was solved by using a separator between two fields (;). I was using dynamic fields linked to email address while creating an outgoing email.
