More and more people are using browsers for every interaction they have with web based services like Office 365. Where this may not always be the case is when it comes to using Outlook.
The desktop version of Outlook is probably the application that most people always have open on their desktop, and many use it more than for simply sending and receiving emails. Many use Outlook to store files, appointments, to do items and more. This is both good and bad. Good in the fact that one application can do this, bad in that in many cases Outlook is not always the best location to handle all this information.
With the move to web based email, many are finding that in fact they don’t need to have Outlook on the desktop and can get away with just using the browser. Using the web based version of Outlook (known as Outlook Web Access) provides people the ability to work with their emails, calendar and contacts where ever they have access to a browser and the Internet.
The desktop version of Outlook currently has more functionality than the web based equivalent, however the browser version is catching up fast. Given that most people don’t use anywhere near the fully functionality of Outlook on the desktop, the web based version makes sense.
It is also important to remember that Outlook Web Access is not only a feature of Office 365, it is also available with most versions of Exchange server. This means that if you are using Outlook on the desktop, chances are you can also use it via a browser. If you can, give it a go and see whether it does indeed do everything you require.
