In
a mixed Microsoft
Exchange environment, public folders
can be replicated from Microsoft
Exchange 2000 Server or Microsoft
Exchange Server 2003 to
Microsoft Exchange Server
2007 Service Pack 1 (SP1).
However, in some
cases, the public folder replication messages stay in
the MapiDelivery queue.
These messages
are retried
periodically on the Exchange Server 2007 SP1 server
that has the Hub Transport
role installed.
Therefore, the Exchange database grows quickly
and exhausts
the disk space.
Additionally, the following warning or error messages are logged repeatedly when this
problem occurs.
