Start recovery for the affected account
Review the finding from Verify Saved Backups. Make your Backup Locations available, then open Manage Account → Maintenance and choose Recover Missing Messages.
For mail marked Missing from source in Browse, follow the instructions for restoring a deleted message.
Where Horcrux looks for each message
- Horcrux starts with the Primary Backup Location and prefers local copies before remote ones.
- When it finds a saved copy, it verifies the recorded size and SHA-256 integrity value before using the file.
- If none of the locations can supply a valid copy, Horcrux asks the original email provider for the message.
Another Backup Location can supply a saved message even after you have deleted it from the live account.
Review the recovery result
Horcrux rebuilds the affected indexes, verifies the repaired backup, and reports how many messages came from Backup Locations and how many came from the provider. If there is no valid copy at either source, the result lists the individual failure.
You can exclude a known message from repeated verification alerts. The global Mute integrity alerts setting silences notifications while keeping the findings visible in account health, verification history, and Jobs.
