Once upon a time, BlackBerry gave away email addresses to use with the purchase of a BlackBerry device, from a participating carrier. The format would be name@.BlackBerry.net or Blackberry.com. So the address might have looked like this: FelixTheCat@Rogers.BlackBerry.net. Well, lately Mr. Cat has had problems getting that email address to work, and with good reason. As with many things from their past, the Canadian manufacturer has apparently decided to 86 it once it gets the number of hosted users down to a small amount. Once the email address is moved to a new BlackBerry 10 phone, mail will be forwarded to the new account for one year and not one second longer.
To set this up, you will need to have a new email provider, like a GMail account for example. You can do this online by visiting the sourcelink, finding the correct service provider you use, and clicking on the link. This will bring you to an easy to use form that will require you to type your new BlackBerry.net address and confirm it. There are also instructions on how to arrange the forwarding directly from your BlackBerry Z10. The regions affected are Canada, Europe, the Middle East and Africa.
You can arrange the forwardiing of email from your BlackBerry.net address straight from your Z10
BlackBerry says it will forward your mail from the BlackBerry.net or BlackBerry.com address for exactly one year from the date you register, so if this pertains to you, why prolong the wait. Your BlackBerry.net or BlackBerry.com email address is not functional now, anyway.
