If you experience issues when performing in-place upgrades of Azure AD Connect from previous releases, or discover that the synchronization scheduler does not work as expected, these issues can be caused by issues in version 18.104.22.168.
Fortunately, these issues have now been fixed in the recent 22.214.171.124 release of Azure AD Connect.
Full set of new features and fixes:
- Upgrade from earlier releases does not work if installation is not in the default C:\Program Files folder.
- If you install and unselect the Start the synchronization process option at the final phase of the Azure AD Connect installation wizard, and later re-run the installation wizard, this will not enable the scheduler.
- The scheduler will not work as expected on servers where the date/time format is not US-en. This error will also block
Get-ADSyncSchedulerfrom returning correct times.
- If you installed an earlier release of Azure AD Connect with ADFS as the sign-in option and upgrade, you cannot run the installation wizard again.
