First, make sure your connection settings are correct. More information about different connection settings can be found here on our help webpage (https://gearmage.com/maildownloader_howto.html#settings).
If you are using Gmail, you may be asked to enter credentials over and over again from within the program. This authentication "loop" can occur in the following cases:
- The mail server settings (host, port, TLS and protocol) are not correct
- The program cannot connect to the host, port possibly due to a firewall or some other block when connecting to that host/port
- Your internet connection may be down
If you can fix the above issues then this should work and proceed.
You may also be behind a firewall or proxy. If that is the case please configure the following:
<defaultProxy enabled="true" useDefaultCredentials="true"> <proxy usesystemdefault="true" bypassonlocal="true" /> </defaultProxy>
<defaultProxy> <proxy proxyaddress="http://[proxy address]:[proxy port]" bypassonlocal="false" /> </defaultProxy>
And see if that helps.
