Offline OWA

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

Outlook has always been able to work offline. I don't know of any 3rd party solutions for Offline OWA though.

Thanks for the replies.  The information given is well meant but I knew this already.  I have been using Outlook over VPN for many years but I now need to use a more up-to-date version.

My question is in respect of Outlook 2013 which is normally Cloud based as I understand it.  What I want to do is run Outlook 2013 without an internet connection so that I can see historical email and prepare emails for sending once an internet connection is possible.  Typically this will be on flights to and from the UAE.  I can currently use OWA in the UAE but Outlook over VPN is not possible as IPSEC protocols are outlawed in the UAE.  Cloud is available in the UAE and therefore I plan to change from OWA to Outlook 2013.  I can only do this if Outlook 2013 can actually work without a Cloud connection.  I can will need to set-up my UK based Exchange 2003 server as the mail server for Outlook 2013 via the Cloud.

So this is going to be quite a difficult technical process to set-up I suspect but I want the best of both worlds - i.e. I want to avoid having to spend a lot of money setting-up a new Exchange 2013 server but have a flexible offline and online Outlook.

I am running Exchange 2003 as stated in my original post - it is however the SBS version (I suspect that has little bearing on the issue though) I am using a mix of Outlook 2003, 2007 and 2010 on various PCs.  I have spent many hours trying to get Outlook to attach to my server via SSL without any success.  On this basis when in the UK I can use Outlook over VPN in static locations and then OWA when I am working away from bases.  OWA has served me well but the lack of offline access to email is not getting to be a major issue.

So is it possible to install Outlook 2013 on a PC based in the UAE and use a standard internet connection to get Outlook to connect over an SSL connection?  Is Outlook 2013 installable software or is it simply accessed over the Cloud - that is the crux of the question I have and an answer to that question will help enormously.
Actually, Outlook 2013 is not supported on Exchange 2003.

If this is an SBS server then the configuration for Outlook Anywhere is very simple but it does require you have an SSL cert signed by a 3rd party.

I already have a SSL cert via Go daddy.

OK so Office 2013 is not the answer if I retain Exchange 2003

Perhaps the way forward is to go for Office (Outlook) 2010 and try again with Outlook Anywhere.  I can then use Office (Word & Excel) 2010 with the Cloud for documents that I need to be able to get from many locations in the UK and in the UAE.

I am beginning to see a way forward.  I will start experimenting with Outlook 2010 after NYE party is over and I've recovered from the after-effects.

Thank you for your help

Exchange 2013 cannot be installed in an Org with Exchange 2003 servers. They must migrate to 2007 or 2010 before introducing 2013.

Thanks for all the advice.  The project was abandoned but the information was useful as background knowledge for any future work.
