Error code 700003

Question

Error code 700003 in Microsoft Teams typically means that the device has been removed from the organization's system—in this case, Santa Rosa IT likely kicked your dad's computer out of their network. This could have happened due to policy changes, security restrictions, or administrative actions. ******@santarosa.12.fl.us. can you fix it so i can do my homework

Answer 1

Error code AADSTS700003 indicates that the device object was not found in the tenant directory. This typically means that the device has been removed from the organization's system, which could be due to policy changes, security restrictions, or administrative actions. To resolve this issue, it's recommended to engage with the home tenant administrators to determine when and why the device object was deleted. Depending on the device registration/join type, different actions may need to be taken to re-register the device.

For example, if the device is Microsoft Entra registered, you may need to disconnect it from the work or school account and then register it again. If it's Microsoft Entra joined, running a specific command in PowerShell could help recover the device.

Answer 2

Hello Johnson, Joshua,

The error you're seeing—Microsoft Teams error code 700003 is often done by your school or IT department (in this case, Santa Rosa IT) for security or administrative reasons

What you can do:

Since this is a school-managed account, you won’t be able to fix this on your own. Here’s what you should do:

1 - Contact your school’s IT department (Santa Rosa IT):

• Ask them to re-enroll your device or reassign your account to a valid device.

2 - Use a school-issued device (if available):

• If you have access to a school laptop or tablet, try logging in from there.

3 - Try a browser login:

Even if no device authentication is explicitly requested, Microsoft Teams may attempt to read device info using an existing Primary Refresh Token (PRT). If the device is no longer registered in Azure AD, this results in error 700003.

You can try the following steps to re-register the device:

> Step 1: Clear the AAD Device Registration Cache

• Press Win + R, type regedit, and press Enter.
• Navigate to:HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\AAD\Storage\
• Delete the entire Storage key (right-click > Delete).
• Close the Registry Editor.

> Step 2: Re-register the Device

• Open Settings > Accounts > Access work or school.
• Click + Connect and sign in with your school account
• Follow the prompts to rejoin the device to the organization.

> Step 3: Restart and Try Again

• Restart your computer.
• Open Microsoft Teams and try signing in again.
