system failure: Folder sync failed with Zimbra accounts
I'm using ZCS Open Source Edition 7.1.4 (zcs-7.1.4_GA_2555.DEBIAN5_64).
I allow an user to have an external account (IMAP). This account is another account on the same Zimbra server.
All was fine, but since few days, the user have this message when he loggin :
The message concern the external account. No trace of this message 24428 via zmmailbox. No trace of this message in MySQL database, seems it never exists ... :'(
system failure: Folder sync failed, system failure: Synchronization of folder '/xxx/Junk' failed, system failure: Server returned no response for UID FETCH 24428 BODY.PEEK
How can i find this message, delete it or fix this error ?
Many thanks in advance.
