I am having the same problem. I have a custom domain hosted by Yahoo on their servers (pop.bizmail.yahoo.com and smtp.bizmail.yahoo.com). I set up Outlook (not Windows Live) to retrieve and send e-mails through that custom domain. This worked fine for many
months, then suddenly....
The way I set it up is as follows:
1. My primary alias was an e-mail address on my custom domain
2. A send/receive account was set up using the pop/smtp server settings provided by Yahoo
As I said, this worked fine for many months, and then just stopped, with an error message saying "we were unable to sign in to your pop server, please make sure your username and password are correct" (which they were).
I have tried setting up a different primary alias (a *** Email address is removed for privacy *** address) and then removing and re-adding the custom address as a new account - but I still get the same error, and Outlook won't add the new account.
I am now able to SEND mails through Outlook using my custom domain (i.e., using my custom address as an alias), but completely unable to retrieve mails. Repeated attempts to set up the custom account again as a send/receive account are unsuccessful - Outlook
simply appears unable to see and talk to Yahoo's servers, I keep getting the same error message (as above).
Please note:
1. The pop/smtp settings, ports etc. are correct - exactly as provided by Yahoo, and the same as what was working for months before the current problems
2. My username and password have been correctly entered (repeatedly!)
3. I travel a lot, and am often in different time zones around the world - I never change the local time on my computer. I am wondering whether the problem may be due to:
a. Time differences or mismatches creating sync problems
b. Connections through servers in different countries creating the problem
Can anyone help? I just want Outlook to talk to Yahoo and get me my mails!!!!
Thanks!! :-)
