I can't send e-mail whether I use a client such as outlook. or even if I go directly to the site of my pop mail provider. I can recieve just fine. No one else in my team is experiencing this issue.

Given 's symptom — incoming mail OK but every send attempt fails (both the mail client and the provider's web interface) — the fault lies with the outgoing path or something the provider is doing to the account or IP. 's request for the provider name is exactly the right detail, and 's pointer toward network-level blocking is a useful lead to follow.

Quick isolation checklist (do these before changing account settings): try sending from a different network (tether a phone or use another Wi‑Fi); try sending from another device on the same network; test the provider's webmail in a different browser with extensions disabled; temporarily disable any antivirus/mail‑scanning and any VPN/proxy (only for a short test). If sending works on a different network but not on your normal one, the problem is the network/ISP/router. If other people on the same network can send but your laptop cannot, the problem is local to the laptop.

Verify the outgoing-server configuration; common correct fields look like this:

Outgoing (SMTP) server: smtp.provider.com
Port: 587 (STARTTLS) or 465 (SSL/TLS)
Require authentication: Yes (use full email address and password)
Encryption: STARTTLS or SSL/TLS enabled

Also ensure the mail client is set to authenticate for outgoing mail and that the username format matches the provider's requirement (sometimes the full address, sometimes just the name).

If both client and webmail fail from every network, suspect an account hold, sending limit, or provider-side block and contact the provider with the full error text. If the problem isolates to your network, talk to the ISP or check your router/firewall rules. When asking for help, include the exact error message or SMTP/HTTP response code — those lines are what support teams use to pinpoint the cause.

Can I be cheeky and ask who the POP mail provider is?

It could be your internal firewall or your ISP blocking port 25. Try this from a command prompt and see what you get:

telnet <email server name> 25

If you get a HELO back you are connected to the pop server. IF not check your firewall and see if port 25 is open.
