For some reason this client tells me there is one email address in a message with an attachment I sent yesterday that must be resolved before it will allow me to poll new messages. When I click on Outbox I see no messages in there.
The Error reads:
“[Exchange Web Services] Sending email failed due to the following: At least one recipient is not valid…”
I know for fact the email is valid
I am on Exchange.
Using Outlook shows me nothing as far as accessing any Outbox.
I am not on any VPN
I cant use this program to retrieve any mail now until it is resolved.
Any Help ???
