Purpose
SAP MAPI contains:
Prerequisites
Under Windows 95 and NT 4.0, the MAPI subsystem and Microsoft Windows Messaging (a MAPI-compatible client) come with the operating system.
Under Windows NT 3.51, you must have installed the MAPI subsystem and a MAPI-compatible client (for example, Exchange Client for NT) from a separate source before installing the SAP MAPI.
Microsoft Windows Messaging is a version of the Exchange Client with fewer functions. Two noticeable features are missing: A spell-checker and automatic recognition of World Wide Web http addresses. To get these features, you need to install the Exchange Client on top of Microsoft Windows Messaging.
Process Flow

When you have installed the SAP MAPI, the error message Local cache not found is displayed when you start the MAPI client for the first time. This error is caused by the fact that the local cache can only be created in online mode. You should therefore ignore the error message and logon when the next dialog box appears. The local cache is now created.
