Hello Astan, After a bit of experimentation I find I get the same problem on XP using 2.6 for len(body) > 1973, using the os.startfile method. Some light googling suggests this is probably a limit within Outlook itself. If you just want a way to start Outlook programmatically you may be able to work around this by automating Outlook - try googling python outlook automation. If you want to start a default mail client on any machine using the mailto protocol then you'll have to limit the size of your message bodies. You may find that other mail clients have limits too - I doubt that any client (or browser) will accept urls of unlimited size. Cheers, Kev -- http://mail.python.org/mailman/listinfo/python-list
