The error message indicates that backup isn’t actually signed in/initialized, even if a personal Microsoft account is present in the app. To get backup working again after turning it off, re-establish the backup account and backup state:
- Open Microsoft Authenticator on the device.
- Go to Settings (tap the menu icon, then Settings).
- Under Backup:
- Turn Cloud Backup (Android) or iCloud backup (iOS) off if it appears on, and confirm deletion of any existing backup.
- Turn the backup toggle on again.
- When prompted, choose Continue or Change account and explicitly sign in with the personal Microsoft account that will hold the backup.
- Confirm and complete the backup setup.
If the “Something went wrong” message appears because the app is not properly signed in for backup, these steps force a fresh sign-in and backup creation.
If the problem persists, use the in‑app Send logs option as suggested in the error so that support can review the failure details.
