In the middle of a migration from SBS2003 to SBS2008 Standard. Have got as far as moving the Public Folders but this replication is still ongoing. Mailboxes are still on SBS2003 - not touched yet.
Incoming email is arriving at the public folders (a rule in place for each mailbox to copy each inbound email to a public folder) but is not going to the mailboxes and mailboxes cannot send - HELP! Inbound SMTP feed is to the new server.

How do I get the new server to forward email back to the mailboxes on the old server? Tjought it was automatic during migration.

Did you run Small Business Analyzer, Exchange Small Business Analyzer, dcdiag, etc?


The recommended steps are:

1.      Clean out all mailboxes and files from SBS2003 server
2.      Prepare SBS2003 server for Migration
a.      Make sure all updates and patches are installed
b.      Backup SBS2003 server
c.      Verify the network configuration
d.      Raise the functional level of Active Directory
e.      Run the Migration Preparation Tool (updates schema, extends time limit for migration, prepares Exchange for migration

3.      Create Migration Answer File for SBS 2008 migration
4.      Install SBS2008 in Migration Mode
5.      Move settings and data to the Destination Server for Windows SBS 2008 migration
6.      Delete the old Folder Redirection Group Policy object migration for Windows SBS 2008
7.      Optional post-migration tasks for Windows SBS 2008 migration.  After you finish migrating all settings and data to Windows SBS 2008, you may want to map permitted computers to user accounts, enable folder redirection, configure POP3 connectors, or update mailbox quotas on your new server.
8.      Run the Windows SBS 2008 Best Practices Analyzer

Did you do these things?
Hi

I followed the migration document from Microsoft as far as the Public FOlder replication. Basically i think the queues were full of replication data and slowing everything down (the source server was very slow). Now replication more-or-less finished, all OK again.
