Email clients were popular in the past, but as the Internet develops, many users switched to webmail services since they are more practical.

Eudora used to be a popular email client for macOS and Windows alike. It was launched in 1988 and later acquired by Qualcomm in 1991.

The last commercial version of Eudora was released in 2006. Following several attempts to keep it alive, an open-source version of the client was abandoned in 2010.

Even though Eudora is now an outdated email client, some users don’t want to switch, and they continue using it on Windows 10.

Since the email client hasn’t been updated in years, some issues with Windows 10 are expected, and today we’re going to show you how to fix them.

How can I fix Eudora problems on Windows?

1. Install Eudora to the root directory

Most Windows applications will be installed by default in C:Program Files directory. But it doesn’t work for Eudora.

So during installation, be sure to change the directory from C:Program Files to C:Eudora and send the application there.

After doing that, most problems with it will be resolved.

2. Try an alternative email client

switch from eudora to mailbird
