This has been going on for about 5 days, now, where Zimbra doesn't sync for one email and I keep getting "Failure communicating with remote server. Please try again later."

Please note that this is only one email and all the other Yahoo accounts are syncing just fine. (I did have a problem with a different yahoo account last year but that problem eventually got cleared up.)

I have included the error message just in case someone understands it.

The last time I had a problem, with a different Yahoo account, I ended up deleting the problem email and then adding it again. A REAL PAIN!

HELP! Please! Someone!
