How to activate your new Yahoo! Business Email email address depends on the type of email address your administrator gave you: one you access via POP and Yahoo!, or only via POP. (For the moment, you don't need to understand what these terms mean we'll explain in better detail later.)
You can determine this from the kind of invitation you received. Look at your invitation: Are there four sections (option #1), or just two (option #2)?
|Option #1 - POP and Yahoo!||Option #2 - POP only|
