Hi,
If your Azure Active Directory is synced with a local Active Directory, Lansweeper can continue to scan your machines via AD scanning targets. If your Azure Active Directory is not synced with a local Active Directory, you can scan your machines via an IP Range Scanning Target if those machines have a local administrator account which can be used to scan them properly. Without a local administrator account, this will not be possible, unfortunately.
Alternatively, you could also make use of our LsAgent scanning agent for those machines to scan them regularly.
