At work our end-users are on Windows XP and using Outlook Express. Whenever a user composes an email or replies to one, Outlook Express "reads" a static html file located on c:\, and uses the content as a signature. This works perfectly fine.
Now my coworker gave me a simple text(.txt) file with 100+ lines, each line containing a "motivational quote".
My objective is to somehow have a random quote extracted from this text file, and inserted into the static html-signature file.
Since I am limited to what XP natively supports and can't install any additional software such as python, I assume either batch or vbscript would be the proper choice (if not only). I imagine a script which is executed via. the Windows Task Scheduler every 15 minutes or so, which randomly reads a line from the .txt-file, and updates it into the static html-signature file.
Is this possible in any way, or are neither batch nor vbscript capable of doing something like that?
Any help or advice will be GREATLY appreciated :)

You can create a signature template that has embedded variables that are replaced by delayed expansion. Any exclamation point ! or caret ^ literals must be encoded as variables as well:
!QUOTE! = The random quote
!X! = exclamation point literal
!C! = caret literal (probably not needed)
Additional variables could be added to the template as needed.
Here is a trivial HTML template as an example
<!X!doctype html>
<html>
<head>
<title>Random Quote</title>
</head>
<body>
<p><strong>!QUOTE!</strong></p>
</body>
</html>
The following batch file will select a random quote from the quote file and write out the signature file after replacing the variables in the template.
EDIT - I improved performance and slightly altered the limitations by using FOR /F to read the quote line instead of SET /P.
@echo off
setlocal disableDelayedExpansion
::Define the files
set quoteFile="quotes.txt"
set signatureTemplate="template.txt"
set signatureFile="signature.html"
::Define constants for ! and ^ substitutions in template
set "X=!"
set "C=^"
::Count the number of quotes
for /f %%N in ('find /c /v "" ^<%quoteFile%') do set quoteCount=%%N
::Pick a random number of quotes to skip
set /a "skip=%random% %% %quoteCount%"
::Load the selected quote into a variable
if %skip% gtr 0 (set skip=skip=%skip%) else (set skip=)
for /f "usebackq %skip% delims=" %%A in (%quoteFile%) do (
set quote=%%A
goto :break
)
:break
::Read the signature template and write the signature file
::Delayed expansion will automatically replace !quote!, !X! and !C!
setlocal enableDelayedExpansion
>%signatureFile% (
for /f "usebackq delims=" %%A in (%signatureTemplate%) do echo %%A
)
There are a few limitations to the script as written:
; will be skipped;
