I have installed free version of eM Client 6. It is set to close to system tray. I often get an error message “[IMAP] An attempt to connect (My ID) @yahoo.com failed. This could be caused by temporary server unavailability or incorrect settings. Do you want to check the settings?” with two highlighted boxes [Open Account Settings] and [Ignore]. When I click "Open Account Settings, it leads me to setting dialogue where under “diagnostic” I check the settings, which after checking says “OK”. The program then works normally. After some time, it again sets back to old problem and I have to follow the procedures again and again. I use Vista Home with no other problem in any other email program. I do not know what could be the solution? 
Hi, this is known issue with Yahoo’s IMAP authentication servers. Unfortunately it is issue on Yahoo’s side and we can’t do anything about it, we have tried to contact them many times about this issue, but we never had any response from them.

a) None of my email addresses are with Yahoo. Can we just cut Yahoo out of the loop?
b) I don’t have this error message with Thunderbird, Outlook, or Gmail. What is eM Client doing that the others are not, and how could we be like them?
Many thanks.
Hi Burin, this post was originally for someone else as you can see, maybe you have another issue, for which I would recommend starting a new topic and give us a little more information on what exactly occurs on your computer.
Thank you for understanding,
Paul.
Paul, I have exactly the same issue, so if we can solve Anil’s problem, we’ll solve mine, too.
I see that apparently the problem is with Yahoo, but if so, why can’t we cut Yahoo out of the picture? Or, my getting the problem only with eM Client, and not with Thunderbird, Outlook, or Gmail, suggests that there’s something that we can do on our side, rather than wait for Yahoo.
Many thanks for your very quick response.
Since this post is more than half year old I don’t believe Anil will be joining the discussion, as it may have been already resolved by my colleagues.
Can you please make a screenshot of the issue, and give us more information about your setup, what mail service are you using? What version of eM Client are you currently using and start a new topic with this issue?
As Anil’s issue was with a yahoo account this is not the same issue.
Thank you for understanding,
Paul.
