The default configuration for Exchange 2010 has the Address Book will update every 24 hours at 5am.
Exchange 2013 only supports Outlook 2007 (post SP3 and cumulative update), and Outlook 2010 must be at SP1 with cumulative update. For public folder distribution ensure the public folder database is mounted, and at least one server holds a replica.
Also in the properties of the mailbox database, your users are using, make sure it points to the correct public folder database.
This delay between an email account being create and being listed can cause organisational issue, like a users being unable to find the email address for a new staff member. Make sure the OAB you are looking at, has been updated from the GAL. If using Outlook, query the GAL directly, or download the latest OAB. Before you do anything send the user you created a ‘Test Email’ from your own account.
