Microsoft Outlook, one of the elite members of the software applications included in Microsoft Office suite, is not just popular, rather the best email client available. There are many features and functions offered, with which most business communications are made simple, organized and neatly managed. Like any other software, even Outlook is not perfect. There are many possible Outlook problems that may occur while using Microsoft Outlook.
Users of computer applications need to know that the program you are running depends on resources that are held on another system. The other computer we are talking about is the Server and has to be contacted over the Internet.
What are Servers?
There are servers all over the Internet and all internet users use them every day without actually coming across them themselves. Servers work with the local systems behind the scenes. The work being done is locally. This in fact is just a portion of the work your local program does. It may even be performed on some other system.
What are Clients?
Actually, your PC or local computer is referred to as the Client. The term client can also be used to refer to the program accessing various services on the Internet or network.
The application where the client receives services from a remote system is known as Client Server Architecture. It is the client that always contacts with a request for a service. The server gives the response. This simple request/response transaction is known as a connection. Web page to a Web browser usually follows this type of model. Certain applications require the client and server to maintain contact for some time and then exchange different messages.
Now, coming to the connection issue, when you get an error message stating that the server is unavailable temporarily, then it is mostly because the server is too busy to fulfill the request at that moment. Actually, Internet servers have to handle thousands of clients every day, at times even millions. These systems have to divide their workload as a group of servers known as cluster.
Most of the times, the user has little or no control over where the client application goes for services. For instance, you may know that the Hotmail server and the user will not be gaining anything by directing the email client to another server. You will have to wait to for the server to function properly when such Outlook problems occur.
