Starting the week of June 3rd, you may be prompted to upgrade to the new version of Yahoo! Business Mail. The upgrade will be seamless and instantaneous -- everything in your existing Yahoo! Business Mail account (emails, attachments, contacts and folders) will move over.
If you are already using the new version of Yahoo! Business Mail, you will
NOT be impacted and will not need to take any action. If you are using one of our legacy mail platforms, you will be impacted.
