resource unreachable: must authenticate

[beki]

Hi

I'm having problem with zimbra shared folders.
I'm trying to send email using forward or reply from zimbra shared folder and it doesnt work for emails that have attachments and I'm trying to send attachments. If I try to send emails without attachments, it works.

I'm using Zimbra Desktop 1.0.3 build 1691
This works when i'm using Web GUI.
ZCS version 6.0.0

Error message is:
