I have a user who can open groupwise on his laptop, receive email but is unable to send. When I click on the send, reply, or forward, the system hesitates for a few moments and then windows(XP Pro) throws up one of those do you want us to send an error message to microsoft windows. I can proxy into the mailbox and send mail without a problem. I can set tasks and apointments and view the calender without any issues.
