Error message: "MAPI component is missing"
Posted by Daniel Weuthen on 29 Nov 2012 11:26

Problem: When clicking on Open in Outlook in MailStore Web Access, you receive an error message saying MAPI is missing.

Solution: In order to use the Open in Outlook feature in MailStore Web Access, a library called "MAPI" has to be installed on the system where MailStore Server is installed.

MAPI already comes with Exchange Server 2003 or earlier and with Microsoft Outlook. If one of those products is already installed on the system where MailStore Server is installed, no action is required.

If this is not the case, you will need to download "Microsoft Exchange Server MAPI Client and Collaboration Data Objects 1.2.1" from the Microsoft website and install it on the computer where MailStore Server is installed. We provide a shortcut to the MAPI download website via http://www.mailstore.com/?mapi.
