We recently moved from Microsoft Exchange to Office365.  Our Active Directory domain still has two OUs named 'Microsoft Exchange Security Groups' and Microsoft Exchange System Objects'. Are these OUs OK to delete now?  They appear to be empty.

Thanks

So you removed all the on-prem Exchange Servers? You arent managing the objects from an on-prem Exch Server?

Yes. We shut down the last of the on-prem Exchange servers and are 100% on O365.

Hi,

After youve verified that all email is being routed directly to the Exchange Online mailboxes, have completed the migration, and no longer need to maintain your on-premises email organization or dont plan on implementing a single sign-on solution, you can uninstall Exchange from your servers and remove your on-premises Exchange organization.

Best Regards.

Thanks.

Just to verify, I will then be OK to delete the two OUs named 'Microsoft Exchange Security Groups' and Microsoft Exchange System Objects' from our Active Directory hierarchy?
