I'm running across a similar issue with the same vendor.

However, I'm receiving a "permission denied" error code 3....user does not have required permission on path/x/outbox message.

I tried changing the preferred SFTP version to 4, but that didn't work.

They told me to turn off Shell Access, but to be honest I have no idea how to do that.

How's that similar? Please start a new thread and attach a complete log file.

Thanks for sharing this.

Anyway, can you send me an email, so I can send you back a debug version of WinSCP to track the problem? Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.

There's no general solution. Every problem related to this error message is different. Pleae post your log.

I would like to second that. If you would kindly post the solution, it would be helpful. Thanks!

it would be great if you'd actually shared the secret solution to the problem, otherwise this post is useless for others (-> delete the post since it is useless).
