Now and then we get errors in our Azure AD Connect syncronization, or that said – my customers get errors.
And every now and then there is a error wich are not easy to spot what can be wrong.
In this case the sollution was not that easy – but when you think of it, it makes kind of sense sort of.
So this is the Error i got.
Looking into Azure AD Connect it throwed a error on syncronization.
After some investigation back and forth i with the GUID who did not match the Azure AD Sync error – i found out that a deleted group was configured as a licensing group within Azure AD. Therefor when it was deleted from On-prem AD it could not be deleted in Azure AD since it still was in use.
By removing it from the license sku it removed it self on next sync.
