This sounds really dumb and it's probably simple but I just cannot find it !
I run Zimbra desktop 0.92 (build 1418) on an OpenSUSE 11.0 (I think) Linux box. It has one ymail account and one yahoo.com account and for both, the only things being synched are the Inbox and the Contacts.
It used to be that whenever I sent from either account, a copy got stored in the Sent folder on my machine. But I'm alarmed to find that for ymail the last one was 7th December 2008. For yahoo.com, it was 28th November 2008 (although I don't use that one so much so maybe I didn't send anything from that account between those dates).
Checking the "Account Setup", when it comes to synchronising I see that you get the choice for the inbox but for the rest it's all or nothing. Is that right for yahoo accounts ?
Either I am missing something fairly basic here (in which case, sorry !) OR something changed toward the end of last year. I favour the former because I can't believe that something so basic hasn't been noticed !
Can somebody please put me out of my misery ? LOL !
UPDATE: The answer to this basically seems to be to set some kind of synchronisation and then click on "Save & Validate" so that the server gets nudged to start synchronisation. See my post here.
