Hi ali,

If your ADFS is down you have to convert your Tenant from Federated to Standard and have AD Connect configured to sync with password.

Is not automatic and have manual process that can take time, but is a backup solution.

Many organization need ADFS regarding the security reasons to do not authenticate directly on Office 365 and now is a choice of organizations, in the past was not possible to synchronize passwords and ADFS was the solution, now you have the option to decide.

In most cases it's now better to use PTA than ADFS, more secure, less infrastructure required.
