- These instructions are intended specifically for setting up an email account in Mozilla Thunderbird 38.3.0 on Mac OS X 10.11.1.
- While the steps should be similar across platforms and operating systems, they may not necessarily apply to older versions of Thunderbird.
- For help with general email account settings, see How to Set up Any Email Client.
You can edit an email account that already has been configured in Thunderbird, for example should you decide to switch between non-SSL and SSL settings or change the server’s connection port. You change the connection type between standard (non-SSL) and secure (SSL) by changing the hostname and port for the incoming and outgoing servers.
