EXOAuthenticationPolicy: Cannot change resources

[ricmestre]

Description of the issue

After creating the policy it's not possible to change it, this is because Set-AuthenticationPolicy doesn't work and always fails with error message Object reference not set to an instance of an object, the solution is to just remove the current policy and re-create it with the new settings.

Looping in some folks from the EXO Product Group. I would rather have us spend time fixing the Set- cmdlet than working on a workaround.

[ricmestre]

Myself included, but at least there's a workaround if it's something that it's not easily fixable.
