Hi @Stephanie, Thanks for your question inside Q&A.

The v. you note here and when I look at the release history page for Azure AD Connect/Entra ID Connect as the new name is here: https://learn.microsoft.com/en-us/entra/identity/hybrid/connect/reference-connect-version-history I see that your v. is very old.

For the fix here, you need to upgrade the intance of the Azure AD Connect server.
