We recommend that you create a test mailbox in %BRAND_OFFICE_365_SHORT% so that you can test your hybrid configuration. You use the New Remote Mailbox wizard in the %BRAND_EXCHANGE_MANAGEMENT_CONSOLE% (EMC) on an %BRAND_EXCHANGE_ONLINE_SHORT% 2010 server to create a test mailbox. If you want to create more than one test mailbox, you'll have to use this wizard for each test mailbox. You can't use the wizard to create multiple test mailboxes. After the test mailbox is created, you'll want to verify that mail flow is working properly by sending messages and meeting requests between an on-premises mailbox and the %BRAND_OFFICE_365_SHORT% test mailbox.
