Hi,
We have deployed Azure AD Connect in our company since 2 years now and the last few days I'm getting the following error regarding to a specific user:
Get single object failed to get object User_<Object ID>. Tracking Id: 00000000-0000-0000-0000-000000000000, Exception: Exception details =>

Synchronization Service Manager shows no errors, Azure Active Directory Connect Health shows no errors as well.
The specific user used to sync with Azure AD but since his retirement (about 6 months ago) we disabled the AD domain account (it is still there but in a disabled state), stopped the synching with AAD and we converted the mailbox to a shared mailbox in Office365 portal.
We're using an Office 365 Standard subscription, the DC is a Win2012 R2 running the latest Azure AD Connect version (1.6.16) and as far as I know nothing have changed since the last few days I'm getting those errors.
Can you please help?
