Azure Active Directory synchronisation attempts failing
Unhealth identity synchronization notification.
Azure Active Directory did not register a synchronization attempt from the identity synchronization tool in the last 24 hours for <Company>
Solution
There are a large number of reasons why this might be affecting you, however in this specific instance we needed to ensure the Microsoft Azure Active Directory Connect was not stuck at ‘required to upgrade’ screen.
Connect to the AD where you have installed the Sync tool and confirm.
Perform the upgrade as necessary
I then had to spend nearly as hour trying to discover what username / password was configured on this damned account as it was not working with my Azure portal login (portal.azure.com).
As this was a partner subscription from the Microsoft Action pack the original configuration was setup under portal.office.com, also as password synchronisation was setup as part of the AD sync, the previously updated on prem passwords had not synced with Office – so no one could log in with their new passwords.
So
- I ran password recovery for the @xxx.onmicrosoft.com account
- Accessed the portal.office.com and confirmed all else was ok with the subscription
- Setup On Prem AD Sync again with the recently reset user and password.
- Finally we can complete the upgrade.
- Upgrade completed
