I was trying to assist the phone vendor in sending voicemail message via email. Clients are using Outlook, they have an Exchange mailbox and pop3 email account which was set as default. They used ISPs outgoing mail server. Everything was working fine for almost 3 weeks until today.
I ran the Set up your Internet Address wizard and now the Outgoing mail is not working either through the ISPs SMTP server or the Exchange Server.
The website/email is hosted by a third party vendor. Our ISP is Cbeyond.
Can the effects of the Wizard be undone?
