How to refresh Schema in Primary & Staging Azure AD Connect servers.

Question

We have Primary & Staging Azure AD Connect Servers.

We have made changes in Active Directory Schema as part of Exchange CU upgrade process & we want to refresh the schema in Azure AD Connect.

I would like to understand the process to refresh the Schema in Azure AD Connect Primary & Staging Server.

Thanks,
Raj

You generally only need to do this when installing Exchange for the first time in the forest, a completely new version of Exchange, or if the CU introduces an attribute that AADConnect needs to sync to Azure in order to support some function.

In other words, its not something typically required.

If you look at the link of introduced schema changes in 2016 and 2019, if you are already on those versions and you upgraded to the latest CU, there is no need to refresh the AADConnect schema, so you are good:
