You're not the only one. Sorry but as only one of my friends pays for this Yahoo SMTP/POP3 I can't check today why Yahoo's changes broke it.
Since you are adverse to checking things can you supply what you used so I can check it out?
About 3 months ago, my yahoo account which is linked to WLM
(I pay a yearly fee for this) stopped working. No, I didnt make any
chages in my computer the day before, this just "happened". The message
I received is: Unable to send or receive messages... etc etc.
Windows Live Mail error: 0x800CCC0F. I was unable to fix this and after
a month and some days, all of the sudden, all my emails went through!!
and again, I havent done any changes in my computer. Now this same
problem happened again and I really dont want to wait another month or
so for this to be fixed out of the blue. I deleted the account, configured again, checked the ports so please dont give me that advice. it doesnt work.Any ideas PLEASE?Thank you!
