sync error 0x800488eb

I have read and followed all the suggestions posted and still have the problem. after i repaired windows essentials i reconfigured my email account. now when i add my email account and click on it iget a blue banner at the top of the window stating " syncing this account check back in a few minutes to read your messages" i left it once for 24 hours and it never did sync. i have reconfigured my account at least a dozen times now and the results are the same. i have two other accounts on the system both are imap in and smtp out. they work fine. can you help?
