Azure AD sync error Duplicate Attribute-Object Type- Contact

Hello,

I would like to know the process for resolving AD sync error for the Duplicate attribute where object type is contact. I have reviewed process for object type User where we can convert Object GUID to immutable id, however the contact or distribution groups do not have any Object GUID- so am stuck in resolving these errors.

the error I have - We detected that an object with UserPrincipalName “null” cannot be synchronized because another object already has the same value of “SMTP:*******@****.com” as its ProxyAddresses. "

Please guide me on how to resolve these, I have 300 such errors for distribution groups.

Thank you for your time.
