Email button on Preview doesn't work

[wincan]

When I press on the the Email button on the Preview button, nothing happened. The mail message window doesn't show up.
I got a Result of 453 = VERR_MAIL_FAILURE on the AfterMail event.
VPE.MailWithDialog = True
VPE.IsMAPIInstalled returns 1

Any ideas what else I have to check? Thank you!
