Hi guys,
It's relatively easy. On first starting TB with no account, cancel the wizard. The use "Edit" -> "Preferences" or "≡" -> "Options..." -> "Options..." to get to TB's configuration pages. There, use "Advanced" -> "Certificates" -> "View Certificates" -> "Servers" and finally "Import..."
After you've imported the needed cert, you can re-open the wizard with "Create new account".
You can also use this method to import a self-signed certificate authority if you want to run your own signing operation.
How does he do this at scale Phil?
It appears that if you delete all the unsigned certs, then set up the account using all the proper ports and auth types, then just restart thunderbird, it works as expected. Upon restarting thunderbird, it will prompt you to "confirm security exception", then it automatically imports the cert for 993. It somehow seemed to automatically import the cert for 587.
Can someone else confirm that restarting Thunderbird is a way around having to manually import the certs or change them later through the account settings menu?
Does anyone have any experience with configuring Outlook to use self-signed certs?
Thanks, Alex
