    Hi

    I have an exchange 2003 server with 8 domains.

    I'm planning to migrate all 8 domains over time to the cloud with exchange online and office 365

    I have migrated my first domain and all is working fine apart from on-premise users to cloud users.

    I don't use co-existence cloud and on-premise are completely separate.

    I have removed the recipient policy for the migrated domain from Exchange 2003 and in AD i have deleted the mailboxes (Right click exchange tasks, delete) of the migrated users and ran the clean up agent in ESM but they still exist in the GAL of on premise users hence email does not flow between On-Premise and Office365 users.

    What are the correct steps to remove email attributes from all migrated users in AD / Exchange post migration.

    So the domain in question doesn't exist in AD / Exchange and those migrated users appear to have no on premise mailbox or exchange attributes.

    Thanks

    Hi

    I fixed my issue so if it helps anyone, what i did was removed the recipient policy relating to the migrated domain from the exchange on-premise

    Deleted the mailboxes  so that the users were no longer mail enabled

    then i updated the recipient update policy

    then i had to rebuild the Default Offline Address Book to make those users disappear from the GAL see this KB http://support.microsoft.com/kb/905813

    and finally download the GAL again within Outlook 2010 and now i can email from on-premise to Office365 tennency.

    Happy Days

    Spudney,

    Thanks for all the information.  Could you clarify what you mean by "updated the recipient update policy"?  Do you mean that you simply right-clicked on the Recipient Update Service for migrated Domain, for the Enterprise Configuration, for the Root/Parent Domain and selected "Update Now", or did you delete the Update Service for migrated Domain?

    Again, many thanks for all this information.

    Sincerely,

    Tim Banks

    Hi Tim

    I just updated the default recipient policy that the previous IT company had implimented, they lazily had added all 8 domains to the default policy so that every user created recieved 8 smtp addresses :(

    so i just removed the domain from the default recipient policy i was migrating to Office365 so that all traces of example.com were removed from the exchange 2003 org then i deleted the mailboxes (export/migrate first :) ) for the users with example.com being migrated to Office365 so essentially they had no exchange tabs in AD then inside exchange system manager rebuild the default offline address book then finally download the GAL again within Outlook 2010 and now i can email from on-premise to Office365 tennency.

    hope this helps

    to rebuild the Default Offline Address Book to make those users disappear from the GAL see this KB http://support.microsoft.com/kb/905813
