I am trying to add an email account and when I have put in all the details, supplied by my service provider, I get an Authentication failure notice.

I cannot set up this mail account and my service provider cannot help as he says it is a fault or lack of a certain update/service pack issue.

I have Outlook for Mac 2011 Version 14.4.5 (141003) and a MacBook mid 2010 Unibody.

Help
