The below event is noticed on the Hub/Transport servers:

Log Name: Application

Source: MSExchange Store Driver
Event ID: 1020
Level: Error

Description:

The store driver couldnt deliver the public folder replication message "Hierarchy (PublicFolder@contoso.com)" because the following error occurred: The Active Directory user wasn't found
 
This happens because we assume that if a Servers container exists, there will be a System Attendant object inside it. However, in an environment where Exchange 2000 or 2003 previously existed, and all those servers have been removed, you probably have a First Administrative Group or some other Administrative Group still hanging around with a Servers container, but no servers inside it. When the Exchange 2010 Store Driver stumbles across this empty Servers container, this error is the result.
 
To work around the issue, get rid of that empty Servers container. Exchange System Manager won't let you delete it, but you can use the ADSI Edit tool to remove it. Just be sure that the Servers container you are deleting is one that has nothing in it!
 
To delete using ADSIEDIT:

Start -> Run - > ADSIEDIT.MSC -> Connect to Configuration -> CN=Services -> CN=Microsoft Exchange ->CN=(Site Name) -> CN=Administrative Groups -> CN=First Administrative Group -> CN=Servers
