Unlike with Hotmail (Outlook), sending, receiving, and updating Yahoo via SMTP synching is very laggy.
Does anyone know if this is an eM Client issue or a Yahoo issue? I can have my web browser open for Outlook Mail and also eM Client too. I delete an email via Outlook and it’s instantly reflected in eM Client. That’s not the case with Yahoo.
I can not answer your question directly, however, I do know that there have been
many errors etc with Yahoo recently, perhaps it would be a good idea to contact
Yahoo support or their Forum
Thanks. I’m not aware of any mechanism for the end user (non-premium) customer can contact Yahoo. As far as I know, the issue remains only with Yahoo and it’s not an issue when using other email clients such as Mozilla Thunderbird and Outlook.
