I am trying to integrate Zimbra and Alfresco by creating an account in Zimbra using Alfresco as an IMAP server. Thunderbird is able to view the Alfresco repository as IMAP folders and it seems to work fine. So I think things are OK on the Alfresco side. I am able to setup the Alfresco IMAP account in Zimbra. When I save the account I get the Test Settings message with Status=Success and I press OK. Then after a couple seconds I get the following message:

Account "Alfresco Repository" Failed
system failure: Synchronization of folder 'INBOX' failed, SELECT failed: Error in response, Invalid number format: 1265912165796

Any ideas?
