Hi @Thais Mello,
Since our forum only support English, I can understand your issue by transfer software that if the AD password expires, will access to a certain SharePoint folder also expire?
For this issue, it depend on the setting in your tenant. Password expiration policy configured in Azure AD applies to cloud only users by default. It is possible that the policy you have configured is not getting applied to synced user accounts. If you want to apply same policy to synced users as well, you need to run below cmd:
- Install-Module MSOnline - To install the required module.
- Connect-MsolService - Sign in with Global Admin account of your tenant.
- Set-MsolDirSyncFeature -Feature EnforceCloudPasswordPolicyForPasswordSyncedUsers -Enable $true - To enforce password policies configured in Azure on synced user accounts as well.
