Something really goofy has been going on with yahoo mail and the PRE over the last few days. Mine will authenticate once, and then craps out on subsequent sync's. Usually, I delete and then recreate, but again, it only works for the initial sync and then nothing. Really starting to piss me off...
Yeah I started experiencing that problem near the end of last week. Since I don't use my Yahoo mail account much anymore I just deleted the account from my Pre permanently.
Finally figured it out, after deleting and recreating the account like 20 times. I went in and deleted all of emails the emails that I received prior to the problem occurring and recreated it and now it works! I have had this account for so long I get a crazy amount of emails, guess it was just overwhelmed a little bit (that is my technical assessment of the issue anyway)
