Incomplete mail synch - Yahoo

[jstjst]

Hi
I downloaded and installed Zimbra desktop 7.1.2 to my PC running XP. I have linked 2 Yahoo email ids, validated and saved. On initial sync., or subsequent send/receive, I either get an error, or the process stops after doing a lot of work (200mB downloaded) but many folders are still empty. Same on both accounts. I did previously have this sync working with these accounts, though that was with a different XP PC (Zimbra release I can check tonight).

I looked at the threads and release notes for 7.1.2, and it looks as if a number of Yahoo issues were fixed in 7.1.2.

Is this a known issue ? Are there steps I can take ?

Thanks
