Microsoft released AAD Connect 220.127.116.11 as a download-only version. Although it includes significant changes, including updating the software to use the new AAD V2 endpoint, it was not offered as an automatic update. Turns out that was a wise decision since it breaks the Azure AD Connect Health feature.
3/31/2021: Released for download only, not available for auto upgrade
- This release fixes a bug in version 18.104.22.168 where, after upgrade to that release, the Azure AD Connect Health feature was not registered correctly and did not work. Customers who have deployed build 22.214.171.124 are requested to update their Azure AD Connect server with this build, which will correctly register the Health feature.
If you installed build 126.96.36.199 (either first-time install or as a manual update) please update ASAP to the newest build 188.8.131.52. Get it here: Download Microsoft Azure Active Directory Connect from Official Microsoft Download Center
