I can't send mail - Ms outlook 2000

Hi all,
I installed outlook plugin (gpg4win 1.1.1), the encryption/decrypt from windows explorer it’s work very well; but I can’t send any mail when the buttons encrypt or sign messages with GPG are on.

In fact, I haven’t any error message. Can someone tell me why?, where is the error?.


Can you describe in some more detail
what happens?

I guess you press the send button?
What s happening after this?
