What could cause send failure? Ver. 7.1.30617.0
When closing emClient, a dialog indicates there are unsent messages in the Outbox.
But the Outbox folder is empty.
This is a new error:
‘Sending email failed due to the following error: The user account which was used to submit this request does not have the right to send mail on behalf of the specified sending account., Cannot submit message.’
But messages do send from the Outlook.com web app.
Some of the other errors are:
8:18:36 AM [email protected] [Exchange Web Services] Synchronizing folder ‘[email protected]/Calendar/US Holidays/’
8:20:27 AM at Microsoft.Exchange.WebServices.Data.ServiceResponse.InternalThrowIfNecessary()

8:20:27 AM at MailClient.Protocols.Exchange.ExchangeGenericCommand.Execute(WorkerStatus status)
8:20:36 AM [email protected] [Exchange Web Services] Sending email: Test message
I can’t empty, the Empty Outbox to eliminate the old failed email send items.
Any advice greatly appreciated.
