Devices sometimes keep using cached passwords even after a successful sync. We check that the Work or School Account in Windows Settings is active and linked to the right domain. If there’s a sync error, we disconnect and reconnect the account. We usually check settings like Password Outlook Not Sending or Receiving Email Writeback, Synchronization Rules Editor, and Service Account Permissions to spot misconfigurations.
