AzureAD Password Policy impact after moving from AADConnec sync to Full cloud

Thanks ChristianBergstrom for your answer.

Do you meen "If the password doesn't meet the policy requirements, the user is prompted to try again " : at the user connexion ?

My question is only related to user connexion, because password policy is set to never expire.

I haven't seen any Microsoft document that indicates that the password need to meet the AzureAD password policy at the user connexion.

For me the AAD password policy work like AD password policy : the password policy evaluation is made only when a user change the password, not at the connexion.

Did you have perhaps a reference?

We will activate SSPR only after the Tenant will be full cloud, but all users will not be complient, and want to minimize the impact when Tenant will switch to full cloud.
