# ------ Get default mail client -------
if ($exec) {
$MailClient = $exec + "-compose `"%1`""
}
else {
$node = Get-ItemProperty HKCU:\Software\Classes\mailto\shell\open\command
if (!$node) {
$node = Get-ItemProperty HKLM:\Software\Classes\mailto\shell\open\command
}
$MailClient = $node.'(default)'
}
# TODO check if default client is compatible
# ------ Read email fields -------------
$cmdParams = New-Object Collections.Generic.List[string]
$emailFields = #{"to"=$to; "cc"=$cc; "bcc"=$bcc; "subject"= $subject; "body" = $body}
$emailFields.Keys | % { $value = $emailFields[$_]
if ($value) {
$cmdParams.Add("$_=`'$value`'");
}
}
# Assign ATTACHMENTS
if ($attachment) {
if (Test-Path($attachment)) {
$fullPath = (Get-Item $attachment).FullName;
$cmdParams.Add("attachment=`'$fullPath`'");
} else {
echo "The path `"$file`" does not exists."
}
} elseif (#($input).Count -gt 0) {
# Try to assign ATTACHMENTS parameter from pipeline
$input.reset()
$attachParam = "attachment=`'"
foreach ($filename in $input) {
$fullPath = $filename.FullName + ","
$attachParam += $fullPath
}
$attachParam += "`'"
$cmdParams.Add($attachParam)
}
# ----- Build & run command -------------
$command = ''
if ($cmdParams.Count -gt 0) {
foreach ($param in $cmdParams) {
$command += $param + ","
}
}
$command = $MailClient -replace "`%1", $command
Invoke-Expression "& $command"

If there is no actual requirement to use Thunderbird Send-MailMessage might be an alternative to use.
Using your baseline it could look like the following:
param(
[string]$attachment='C:\Temp\file.txt',
[string]$to='test#outlook.com', # used to specify the email of the recipient
[string]$cc='', # used to specify the email of the recipient of a copy of the mail
[string]$bcc='', # used to specify the email of the recipient of a blind copy of the mail*
[string]$subject='test#outlook.com', # subject of the mail
[string]$body='test#outlook.com', # body of the mail
)
# ------ Get default mail client -------
Send-MailMessage -To $to -Cc $cc -Bcc $bcc -Subject $subject -Body $body -Attachment $attachment -From powershell#example.com -SmtpServer mail.example.com
Most of the fields accept string arrays in case you have multiple CC recipients or simiar.
Notice that you will have to tell Send-MailMessage how to connect to the mail server as it won't magically read your Thunderbird configuration. So you will likely have to include -From, -SmtpServer and maybe even -Credential and -Port depending on how your mail server is configured.
Depending on your requirements you might have to dig a bit deeper and directly use Net.Mail.SmtpClient. There are other questions with examples for it like Send mail via gmail with PowerShell V2's Send-MailMessage.
