my Zimbra email-account (@mavenwire.com) ends up in a failure very frequently - the only solution then seems to be to do a complete reset of my email which is incredibly annoying.

Error message:

Failure communicating with remote server. Please try again later. (debug info)

Debug message: system failure: Unable to get calendar item notes MIME part

Exception:
