How do I fix error 0x80180018 when adding two work accounts? 

1. Create a local account 

1. Use the Windows + I shortcut to launch the Settings app. 
2. Switch to Accounts from the left sidebar and then select Other users (Family & other users in some versions) from the right section. 
3. Next, press the Add account button present next to Add other user option. 
4. On the next window that pops up, click I don’t have this person’s sign-in information. 
5. Next, select the Add a user without a Microsoft account option. 
6. Finally, on the next page, provide the username and confirm the password by entering it twice. 

After you are logged into the local account you just created, perform the next step.

How do I fix error 0x80180018 when logging into a work PC?

NOTE

The following methods should be executed by a network administrator. 

1. Remove enrollment device restrictions

1. Access the Microsoft Endpoint Manager admin center webpage and sign into it by providing the administrator login credentials. 
2. Select the Devices option listed under Device Management on the left navigational menu bar. 
3. Scroll down and select the Enrollment device limit restrictions option. 
4. Next, select the imposing restriction and click the Menu icon (three dots). 
5. Select the Delete option from the sub-menu.  

Imposing a restriction on new devices inhibits them from gaining access hence the 0x8010018 error. Removing these restrictions from the enrolled devices on Intune will help sign in to your work PC successfully. 

2. Enable Enterprise mobility license

1. Visit the Microsoft 365 Admin Center on your preferred browser and enter the login credentials of the administrator account of your organization.
2. Click Users on the left navigation panel and then Active users from the expanded menu. 
3. From the user list, click the user name to which you want to assign an Intune user license.
4. Switch to the Licenses and Apps tab in the user pane and expand the Licenses section. 
5. Here, enable the checkbox preceding the Intune or Enterprise Mobility + Security license. 
6. Press the Save changes button.  

Enabling the Enterprise Mobility + Security license will provide the user account with the required permission to be able to use the service and enroll devices into management. Now the user can sign into the work PC without facing the mobile license-related error. 

So, these are the methods you should implement to fix the error code 0x80180018, which appears when you sign into the work or school account.
