My client suddenly cannot sen or receive emails with his POP email accounts. I reviewed his inbos and other folders to bad or large emails to delete but ther really isn't any. I removed both emails accounts and recreated them them one at a time but that did not fix the problem. I then deleted his Outlook Profile and created a new one and that did not solve the problem either.

Any ideas?

Thanks.

This kind of POP send/receive failure can be caused by the ISP, the PC (firewall/antivirus/add-ins), or Outlook itself. already tried the usual account/profile rebuilds; was right to suggest checking the provider. If webmail works, the server is up — next, isolate Outlook versus the network with the steps below.

  • Confirm server-side: use the ISP webmail/status page to verify mail is being delivered.
  • Capture the exact Send/Receive error text and enable Outlook logging (logging/troubleshooting in Options) for detail.
  • Test connectivity to the mail hosts (POP: 110 or 995 for SSL; SMTP: 25, 587 or 465 for SSL/TLS) to see if ports are reachable.
  • Check Outlook account settings: More Settings -> Outgoing Server -> ensure "My outgoing server (SMTP) requires authentication" is enabled and uses the incoming account credentials.
  • Start Outlook in safe mode (disables add-ins) and temporarily disable antivirus email scanning/firewall to rule out local blocking.
  • Backup the PST, then run the Inbox Repair Tool (scanpst.exe) if corruption is suspected.
  • Try a different mail client on the same PC to determine whether Outlook is the problem.

Note: Outlook 2003 lacks modern TLS support, and many providers now require TLS 1.2+ or SMTP submission on port 587 with authentication. If the server requires newer TLS, update the client or use a current mail app. Always back up the PST before repairs or major changes.
