Does The Trigger Send Email From Shared Mailbox require an O365 license?

Hi All. 

 

Quick question.  I have a newly created shared mailbox with permissions set to: FORWARD, FULL ACCESS, SEND AS and has access to Azure Cloud and AD. My question is, can the trigger "Send Email From Shared Mailbox" still send emails to users without needing an O365 license? If so, why am I receiving a REST API not supported error message?

 

{
  "status": 404,
  "message": "REST API is not yet supported for this mailbox. This error can occur for sandbox (test) accounts or for accounts that are on a dedicated (on-premise) mail server.\r\nclientRequestId: 1087abd0-437f-40dd-9ed2-1d227fce822f\r\nserviceRequestId: 30a5aeec-0f8c-429f-8509-240df0c494e6",
  "source": "office365-ne.azconn-ne.p.azurewebsites.net"
}

Also, how can I tell if this is a migrated shared mailbox or not? Any help would be greatly appreciated!

Hi @hnguy71 ,

 

The error message happens for mailboxes that have not been migrated to Office 365. Your mailbox is likely still on a dedicated exchange server. You will need to request your Outlook administrator migrate your mailbox.

 

Please check the following doc on how to migrate mailbox data by using the Exchange Admin Center in Office 365:

https://support.microsoft.com/en-us/help/2798131/how-to-migrate-mailbox-data-by-using-the-exchange-a...

 

Further, action Send an email from Shared mailbox could send emails to users without an Office 365 account.

 

I have tried to send an email to a Gmail account, which works successfully.

perfect! We were able to successfully migrate the shared mailbox! 

I am having this error but do not have an on-prem shared mailbox. Could there be another issue here @v-yamao-msft ?

 

Edit: To clarify I made a Shared Mailbox via Office 365 and am getting this error when trying to add it as a Connection in Flow/Power Automate
