1st: How can I tell if ISP is blocking ports?
2nd: How can I tell if problem is related to OS?
Problem began since upgrade to Windows 10.
(Business computer, hence I don't know if I have privileges). (Read "Is there a simple way to detect ISP port blocking?" not relevant).
Settings I tried to configure:
Incoming Mail (IMAP) Server - Requires SSL imap.gmail.com Port: 993 Requires SSL:Yes Outgoing Mail (SMTP) Server - Requires TLS smtp.gmail.com Port: 465 or 587 Requires SSL: Yes Requires authentication: Yes
Log onto incoming mail server (IMAP): The connection to the server failed.
Send test e-mail message: Outlook cannot connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet provider (ISP).
Checks I've did:
- I ran a ping test on google's SMTP ports they are blocked. (with & without firewall on).
- Checked multiple email clients.
Open for tests ideas
ISP tells the problem is my Win10?
