Microsoft has resolved a known issue preventing managed devices from receiving the May 2021 Patch Tuesday Windows security updates.
"When checking for updates within Windows Server Update Services or Microsoft Endpoint Configuration Manager and managed devices that connect to these servers," this month's security updates "Might not be available or offered," as Microsoft explained on the Windows Health Dashboard.
"This might also affect Security Only and Internet Explorer Cumulative Rollups, on platforms that receive these types of updates."
Microsoft has resolved the known issue on the service-side, and the updates should start rolling out to affected devices in managed environments.
"If you initiate a synchronization cycle and are still not being offered the updates, please check again soon," Microsoft added.
Yesterday, together with cumulative updates with security fixes for Windows 10 2004 and 20H2, Microsoft also started rolling out new cumulative updates for all supported Windows versions.
