Outlook is one of the most commonly used email clients for personal and business purposes. Sometimes Outlook users may encounter errors when sending or receiving email. This also becomes very uncomfortable for many end users. At first glance, a cryptic error code is very difficult to understand.

So how can you expect to fix the error message that you can’t even understand? Outlook is often affected by errors that regularly stop some activities. As a user, we need to be aware of all of these sudden problems that will arise at all times so that they can solve them as quickly as possible. In the next section we will discuss different solutions for “Outlook Sending Receiving Error 0x800ccc0f”. Let us examine brief information about this error code and some reasons beforehand.

Check TCP / IP Network Connectivity

Assuming that the ping returns an IP address in its response, even though it generates an error while it can get the response itself, the next step is to determine whether the email client can connect to the ports . on the server. This is done through the Telnet utility.

At the email client Windows prompt, type:

TELNET [name/IP of mail server as specified in Outlook settings] 25

If nothing or an error is returned, something, possibly a firewall, is blocking connectivity between the email client and the server. In this case, contact your Internet service provider to determine whether a connection to external mail servers is possible. Check the logs for all firewalls installed.

Disable Windows Antivirus and Firewall

Likewise, the anti-virus program installed on the user’s PC can sometimes affect email functionality.

In other words, anti-virus software that includes the email scanning feature requires additional configuration to use Outlook with the anti-virus program. If configured incorrectly, incoming and outgoing emails can be blocked.
