Contacts disappear, favorites disappear, can't uninstall or replace Contacts app

[rickhantz]

I spend hours trying to re add contacts and favorites. They keep disappearing.

Can I replace my phone dialer with something that directly uses Outlook contacts?

I already had to del Samsung calendar, as it didn't match my Outlook or Google calendar.

I tried to delete Contacts and reinstall, but it failed to uninstall.

You can change your phone dialer - Google voice or Phone by Google are two that come to mind.  I don't know if either will directly access Outlook contacts, but my guess is not.  Why don't you just use Google contacts, then you can access, edit or add your contacts from anywhere on any device and import them to any app.
