I've never even used Outlook on Windows. My school offers Office 2011 for about $15 and I figured I might as well switch from imail to Outlook. The problem is I can't recieve emails from Outlook. Right now Outlook is on a trail..but in a few days I should receive the code for it. Anyway with imail I just gave it my email add. and pw to it and done. However I did the same with Outlook but I keep getting "error code 17900". It's telling me that I cannot add it..and when I try to send/receive emails a window opens up telling me my info or something might be wrong...however I've entered the correct user/email and pw...the other stuff they ask like incomming and outgoing server I have no idea what that is though. The window poping up an error message says this. The server for account "Yahoo" returned the error "[AUTH] Access to this service is not permitted.." Your username/password or security settings may be incorrect. Would you like to try re-entering your password? I have no idea what to do. This problem is going for my Yahoo personal email and for my Gmail school email. I had no problems like this with imail, but Outlook is causing me a headache.
