You can follow this instructions to re-join the device.
Hope this helps.
That worked! Thank you!
How do i know which steps to take? For instance they have listed "For Azure AD joined devices Windows 10 devices, take the following steps:"
If your device is joined to a on-premise AD also, you should follow the instructions from "hybrid Azure AD joined".
If you have only Azure AD then you should follow the instruction from "Azure AD joined devices".
