How to fix the pop3 error 0x800ccc19 in Outlook?

Till now we discussed the main reasons for this pop3 error. Now let’s see how our Support Engineers fix this error for our customers.

1. Scan the registry

The main cause of this error is the operating system registry corruption. A registry is a library system used to store all important data about the operating systems such as configuration, subject, and program settings.

Each time we install a program on the computer, entries are made in the registry.  However, installing and uninstalling programs leaves many of these inputs behind resulting in a number of problems. These include poor system performance, programs that do not work, system instability and random errors.

Therefore we suggest our customers to use maintenance tools such as registry cleaners. This helps to repair the damage and acts as a viable preventative measure.

Sometimes, the corrupted pop3uidl file may be the cause of the 0x800CCC19 error. In this case, we need to locate and delete the file.

Another solution for this is to disable the firewall or uninstall it from the system for a temporary time period.
