When sending or receiving an email with Outlook you may receive an error similar to:

Receiving' reported error (0x800CCC90): 'Your incoming (POP3) e-mail server has reported an internal error. If you continue to receive this message, contact your server administrator or Internet service provider(ISP)

or

The connection to the server has failed. Account: 'pop3.****.net', Server: 'pop3.****.net', Protocol: POP3, Port: 110, Secure(SSL): No, Socket Error: 10061, Error Number: 0x800CCC0E

or

Sending' reported error (0x800CCC92) :'Your e-mail server rejected your login. Verify your user name and password for this account in Account Settings.'

This is a vague error message with a few different possible causes.

1. The most common cause is using the wrong username and password. Make sure in Outlook you have it set with your full email address as the username.  For the password, it's the password for that individual email account. Once the user information's confirmed, try sending a new email and see if the error is gone.
2. Sometimes this is caused by the Outgoing Server using the wrong port number. Please read our article on correcting sending email errors to make sure the right port is used. If this is a recent problem, it's possible your ISP blocked the port you're using.  This can be corrected by simply changing the port as the article above recommends.
3. This error also occurs if a recently updated firewall or virus protector is blocking the email.  To test this, temporarily lower your security settings and attempt to send an email.  If you can, then the anti-virus is the likely issue.

If none of these work, our support team can look into the issue further.  If you are able to, forward a screenshot of the error you're seeing to This email address is being protected from spambots.
