Go to your POP3 and SMTP Tabs and update what your "Host Server address, Port and Security policy is under each tab. Also who is your mailbox providor.
It’s updated, and by the host passwords also changed, but still not working
Administrator has changed the password and still the login credentials are denied, please guide to sort this out
If you are sure the username and password are correct, check your settings.
The port and security policies are specific combinations, so you should have one of the following:
For POP3
Port 995 = Use SSL/TLS on special port (legacy)
Port 110 = Use SSL/TLS if available
For SMTP
Port 587 = Force usage of SSL/TLS
Port 465 = Use SSL/TLS on special port (legacy)
Port 25 = Use SSL/TLS if available
Try one, click on Save & Close and see what the result it. If it still fails, try the next one, etc.
I’ve tried all and still fails, provides the same error, please advise how to sort it out
If the settings are correct, then most probably it is a server issue.
it shows an error in POP3 password, please advise how to recover it
