Invalid email link or an email that never arrives (email_link_invalid)

Symptom

• When opening a link from an email: «The link is invalid, has expired or was already used. Request a new link.» or «This link is not valid. Request a new link.» (API 401 email_link_invalid).
• Or the email never arrives.
• Or: «Email recovery is not available on this service.» (API 503 email_delivery_unavailable).

Cause

• A recovery link lasts 15 minutes and a confirmation link 60 minutes; each works once and a new request cancels the previous one.
• The email program changed or cut the link (for example in a security preview).
• The address is not confirmed, or your organization does not allow email recovery for your account (by default administrators are excluded).
• The service has no email configured, or the address was blocked after earlier bounces.

Fix

1. Ask for a new link and open it at once, in the same browser.
2. Look in the spam folder.
3. Copy the full link into the address bar if your email program cuts it.
4. If the email never arrives, use a recovery code or ask support for help.

When to escalate

The administrator checks under «Manage» › «Email» whether email recovery is on for your account and sending is configured.
