Computers & IT Job - Saint Helena Bay, WC, 7390

My Outlook emails are stuck in the Outbox and wont send. I can receive emails but not send any out. Sometimes they go out but mostly not. I've had numerous Xneelo (email and web provider), Microsoft, & Outlook technitions on the line chaning my IMAP Outlook settings with no joy. I'm also getting Google pop-ups when trying to send an email in Outlook which nobody can explain. Xneelo are saying my IP address gets blocked at their port and that causes my colleagues to also experience the same Outlook outbox issues. I need someone to look at my laptop either remotely or in person to resolve the issue.
