Azure AD Sync Data Mismatch with no data

I have a single on-prem account that fails sync with Azure.
Azure health portal shows a Data Mismatch, invalid softmatch. However, there are no details for the conflicting object:
186866-image.png

The Sync tool shows this feedback:
Unable to update this object because the following attributes associated with this object have values that may already be associated with another object in your local directory services: [Mail OMITTED@racemark.com;].

So, somewhere there is an object with a "mail" attribute. I've used IDFix, and I don't find any duplicate. I don't find anything in Azure w/this address either.
Is there a way for me to look through my Azure tenant for this attribute?

    Hi @Shaun Delorez

    Thank you for asking this question on the **Microsoft Q&A Platform. **

    In the User Attributes on your AD, look for ProxyAddresses attribute

    Look for an alias with that email in your Azure AD, or maybe is a group with that email?

    The mail "******@racemark.com" its duplicate, just is not the UPN

    Hope this helps,
    Carlos Solís Salazar
