If you are a Sky Email Customer today your emails are being migrated over to yahoo mail. You can still keep your address
[email protected] but you need to log in online to activate the switch over or your emails may not work.
You will no longer be able to keep your IMAP settings for your destop pc. If you have POP Settings you should be ok.
Apparently phones and tablets should not be effected by the IMAP settings as its only for desktops.
So if your email does not work then log into your sky email account online and agree to switching your account.
