Web storage services keep Outlook mail, contacts, calendar, tasks and notes synced with the server. (Not all services sync all types of Outlook items.) They can synchronize with your computer, so you can use it to keep updated no matter where in the world you are, as long as you have Internet access and a browser. Be sure to download the synchronization software for your service.
Not listed is Outlook.com. This uses the Outlook Connector (Outlook 2003-2010) or EAS (Outlook 2013) to sync calendar, contacts, and email between Outlook and the Outlook.com server with Outlook, Hotmail, Live, or MSN email addresses.

SYNCING.NET for Outlook is a full featured solution for synchronization of Microsoft Outlook data between multiple computers. All data is transmitted directly between the computers via LAN/WLAN and/or the internet (peer-to-peer). Once selected, the Outlook data is synchronized completely automatically. Users don't need to do anything more and can work with Outlook as usual. Any changes to Outlook items are transferred immediately to all members of the sync network.
There are other online services that claim interactivity with Outlook, but all those that we've investigated use export/import, not real synchronization, which makes them potentially too difficult to manage. However, if you want to check out some other such services, see:
