Using Windows 7 Home Premium 64-bit. Thunderbird 60.9.0 (32-bit) Portable. My profile is in folder Q:\barn\mail-PortableThunderbird\ThunderbirdPortable\Data\profile\ I wish to compare old outgoing server settings (in backup files) to current Thunderbird settings. I do not wish to hide my current Thunderbird folder tree, restore the old version from backup, and look at it with Thunderbird. Rather, I wish to look at the backed-up files and current files without using Thunderbird. How do I do that?

Chosen solution

The prefs.js file, which can be viewed with a text editor, in the profile folder, has several entries that begin with:

user_pref("mail.smtpserver

If the port is 587 (465), the security is STARTTLS (SSL/TLS). The authentication in these cases is normal password, unless you see a reference to oauth2.
