Refresh token: renew access without treating authorization as permanent
A refresh token can let an application request a new access token. It remains a sensitive credential and can stop working when the provider or account owner revokes access.

Who this helps: Readers checking a term before making an outreach or mailbox decision.
Meaning and common confusion
Normal short-lived access-token expiry and failed refresh authorization are different conditions. An operator should inspect the error stage rather than repeatedly reconnecting or changing unrelated SMTP settings. Provider policy and the application's stored state determine the recovery path.
Worked example
This is a synthetic illustration, not a customer result or a live configuration to copy.
Access token expires → application requests renewal
Renewal succeeds → operation can continue
Renewal is rejected → review authorization and reconnect if appropriate
Do not label every expired access token a compromised account.Checks to make
- Keep tokens out of logs and support messages.
- Record the provider error without including credential values.
- Verify the reauthorized mailbox identity before resuming campaigns.
Next step and limits
Use the provider-specific revoked-token guide for diagnosis. A successful reconnection repairs authorization, not uncertain send outcomes or missed reply review. Reconcile those operational effects separately before restarting pending work.
