Thank you for posting your query on Microsoft Q&A, from above description I could understand that you are trying to access your corp resources from an old device and getting error:
Your organization has deleted this device. To fix this, contact your system administrator and provide the error code 700003.
Please do correct me if this is not the ask by responding in the comments section.
As mentioned, this is your old device, I am assuming this device was joined to your organization with corp account but was not used for considerable time. The device would have become stale and required to be reregistered.
If this is a Microsoft Entra joined devices Windows 10/11 devices, take the following steps:
- Open the command prompt as an administrator
- Enter
dsregcmd /forcerecovery
(You need to be an administrator to perform this action). - Click "Sign in" in the dialog that opens up and continue with the sign in process.
- Sign out and sign back in on the device to complete the recovery.
If this is a Microsoft Entra registered Windows 10/11 devices, take the following steps:
- Go to Settings > Accounts > Access Work or School.
- Select the account and select Disconnect.
- Click on "+ Connect" and register the device again by going through the sign in process.
If this is a Microsoft Entra hybrid joined Windows 10/11 devices, take the following steps:
- Open the command prompt as an administrator.
- Enter
dsregcmd.exe /debug /leave
. - Sign out and sign in to trigger the scheduled task that registers the device again with Microsoft Entra ID.
