I get error code 0x800CCC0D / 0x800CCC0F / 0x8004210B in Outlook, what is causing this?

This can be caused by a number of reasons, this is the most common order:

1: A bug in Outlook is causing it, and a restart of the program usually solves it.

2: You are using the wrong port to send. Many ISP:s are blocking port 25 for sending email, so we have opened port 2525 instead.

3
: The antivirus software is blocking/affecting the connection. The easiest way to test this is to disable control of sent email in the antiwirus software.
