All of my emails are not downloading from the server. It happens every couple of weeks. Someone will ask about an email that I never received and when I go to the server, there it is, showing as unread. I am using Outlook 2010 and Yahoo.
Hello,
This can be due to any antivirus installed in your PC. And that antivirus is counting some of the mails as spam and will not allow the entry of mails into the Outlook, rather restricting them to server only.
So disable your antivirus and then check whether the same problem is occurring again!
Or you can also try & open Outlook in safe mode. As it will disable all the plugins or add-ons from your Outlook. Type outlook.exe /safe (do provide the space after exe) to open Outlook in safe mode. Now click Send/Receive and check whether all your mails are now delivered to Outlook or not.
