# Error When Adding a Number to a User’s Internet Fax

## Symptom

When attempting to save a user, an error appears saying, *"Error Saving user. Failed at fax."*

## Applies To

- Admin Console
- X2 license or higher

## Resolution

To resolve this issue, you will need to assign the phone number to a new user, then remove it. This will reset any services the number had setup and allow you to assign the number to the fax.

### Temporarily Assign the Number

1. Log in to [Admin Console](https://sso.8x8.com/sso/login).
2. Navigate to **Users**.
3. Select **+Create User**.
4. Fill in the required fields: **First name, Last Name, Email, and Username**.
  - The information does not need to be valid, we will be deleting this shortly.
5. Under **Services and permissions** select any available service.
  - If you have no more service licenses remaining, you may need to remove another user's license temporarily.
6. Expand **Voice basic settings** and select the phone number you are having issues with in the **Phone numbers** box.
7. Click **Save**.

### Remove the License

1. Under **Services and permissions** click the **x** next to the service assigned.
2. Click **Continue** when it says **Are you sure?**
3. Click **Save**.
4. Select **Users** on the upper left hand corner of the screen and locate the user you just created.
5. Click **More Options** (three dots) on the right side of the page and select **Delete User**.
6. Click **Continue** when it says **Are you sure?**

You should now be able to add the phone number to a user's internet fax. For instructions see [Add Fax Capabilities to a User in 8x8 Admin Console](/support/docs/add-fax-capabilities-to-a-user-in-8x8-admin-console) .

## Cause

This is caused by a bug where after being removed from a user, a number still may not be fully deactivated.
