In Outlook, it gets to "receiving" and after a while quietly stops. Nothing happens! No emails downloaded. It has worked before and downloaded many emails from a couple of yahoo accounts but for the same account, now it is not working, even though there are emails still in the y account.

Will appreciate the help in resolving this.
