I'm sorry if this has already been brought up, but I just purchased a Lumia 830 running 8.1 and outlook is constantly running in the background. I don't sync email, contacts, or calendars. I don't have anything set to back up except photos to OneDrive. Does anyone know why this is constantly running? I have everything set to maximum length syc (there isn't an option to sync manually with outlook). Did I miss a setting? According to my phone, all firmware and apps are up to date. Any help would be greatly appreciated! Thanks!
