Questions tagged [exchange-server]

Questions about automation and APIs related to Microsoft's Enterprise level messaging server.

Microsoft Exchange Server is the server side of a client–server, collaborative application product developed by Microsoft. It is part of the Microsoft Servers line of server products and is used by enterprises using Microsoft infrastructure products. Exchange's major features consist of electronic mail, calendaring, contacts and tasks; support for mobile and web-based access to information; and support for data storage.

Use this tag on programming questions related to the use of this product - questions on installation, maintenance and configuration are better asked on Server Fault, while questions on the use and configuration of Outlook or other email clients are better directed to Super User.
