I am looking to upgrade an existing OWA service based ion Exchange 2003 to a version that supports Offline OWA - i.e. the ability to view email messages and prepare new email messages without a connection to the internet.
I understand Exchange 2013 can do this but I wondered if there were more cost efficient ways of achieving the same thing with the existing server. If I were to adopt Office 2013 and use Outlook 2013, would it be possible to use this offline with a local OST file and thus get access to historical email and be able to prep email for sending once a internet connection is available?
Thanks
