em Client is asking for my password. I use yahoo mail i have 2 account only 1 is asking for password 30 mins. Both have the same settings.

em Client has started asking for my password. I use yahoo mail and have 2 account

I am looking for a replacement programme. I have been very happy with Em Client but this problem is getting to me.

Hi Graeme, did you find a solution as I also use Yahoo and I am having the exact same problem?

This is unfortunately a known issue with yahoo servers. They keep changing their calendar/calDAV source or setting and eM Client can’t then connect to your calendar.
If you do not need your yahoo calendar, I suggest disabling calDAV in the General tab of your account in Menu>Tools>Accounts window.
