## TL;DR
The device still carries an enrollment from a previous organization and Intune will not stack a second one. Remove the old work account and MDM enrollment, verify it is gone, then enroll into the new tenant.

## The query
```text
intune error 0x80180014: device already enrolled with another organization
```

## Use this when
- enrollment fails with 0x80180014
- the device was previously used at another company or in a demo tenant
- reimaged devices still report the old enrollment

## Not for
- 0x801C0003 licensing or authority errors
- brand-new devices failing enrollment
- MDM profile issues on macOS

## Steps
1. On the device, open Accounts, Access work or school, and disconnect the old work or school account. Expected output: the old organizational account is removed.
2. Confirm no MDM enrollment remains in the management settings. Expected output: the device shows as not managed.
3. In the old tenant, if you still have access, retire or delete the device record so it cannot reattach. Expected output: the device record is removed from the old Intune.
4. Reboot the device to clear cached enrollment state. Expected output: a clean boot with no management profile.
5. Enroll into the new tenant. Expected output: enrollment succeeds and the device appears under the new organization.

## Applies to
Microsoft Intune, Windows 10/11, Entra ID tenants. Same pattern applies to re-enrolling Android and iOS devices that changed organizations.

## Variant phrasings
### No access to the old tenant
Local removal still works; the old tenant record goes stale and the new enrollment succeeds.

### Error persists after disconnecting the account
A factory reset clears stubborn enrollment state on most platforms.

## Why it happens
MDM enrollment is one-to-one: a device trusts exactly one management authority. Leftover enrollment artifacts from the prior org block the new one until removed.

## Edge cases
- Autopilot-registered devices may auto-enroll into the old tenant on reset; update the Autopilot registration.
- Demo or loaner devices should be wiped between users to avoid this entirely.
- On shared devices, use a dedicated enrollment account rather than personal accounts.
