Well you have the ImmutableID/SourceAnchor parameter, it's a 1:1 mapping between cloud and on-prem objects. Depending on your configuration, it can use different set of attributes, the default one being ObjectId for single-forest and objectSID/msExchMasterAccountSid for account/resource forest configuration. So check what you are using and then match the values between O365 mailboxes and the on-prem forest(s).

Hi VasilMichev we use ObjectGuid/Immutble ID as 1:1 co-relation.

 

I went to AAD and did metaverse search based and added value as xyz.com and i was able to pull the reports for users whos mailboxes are still mapped to xyz.com

 

I hope i did correct.

    I don't see anywhere on Azure AD or Exchange Online where it specify Forest FDQN. Correct me If I am wrong.
