I am using Windows XP SP2 and Outlook 2003 with Exchange 2003. I have tried
publishing my free/busy information using http and ftp and both give the
error "Write operation failed at URL..." I know the ftp command is correct
because I can issue it at a CMD prompt and it works. I have checked the
password over and over again. When using HTTP it prompts for a username and
password and then gives the error. A few people have posted similar queries
over the last few months but I haven't seen a response which resolves the
problem. Is this just something that doesn't work oris there a fix that I've
missed?

best wishes.....
