I have added an yahoo e-mail account to my bb , suddenly my outlook default contact list disappear now yahoo is active and when iam trying to sync outlook is not sysnicng ,, what to do
I can't remember exactly what is the fix, but look in Settings for a way to change your default email account. You might do the same thing in Contacts and Calendar. Hit the menu button and choose Options or Settings and look in there.
Basically Yahoo has taken over as the default account and is using Wireless Sync. That can break your Desktop Manager Sync to Outlook.
