Hi.

I've a single installation of Z802, upgraded to .3, on which I cannot damn configure an external imap account.
Whenever I try from any Zimbra account I get an error saying the folder already exists. but it's the external account wizard creating it! Before I add the account the folder doesn't exist!
The same happens if I try adding the account via CLI using zmmailbox. I captured the following output from mailbox.log:
Code:
