File Connector Mail Archive Indexing Deployment Overview
Install the Microsoft MAPI component.
The File connector uses the Microsoft MAPI component to access the content of mail archive files. This component must be installed on the Coveo Master server (see Installing the Microsoft MAPI Component for Mail Archive Indexing).
Create a custom document type set.
In the search results, the URI of archived email results cannot be opened in the original mail application. The solution is to use the Quick View to open a cached HTML version created in the unified index when the item was crawled. You need to create a special document type set to do so (see Setting up a Document Type for Mail Archive Indexing).
Consider creating an optional mapping file.
By default, the file crawler uses the NTFS permissions on the mail archive file to set the permissions for each mail archive item in the unified index. You need to create and use a mail archive mapping file when you want to override these permissions, index password protected mail archive files, or make mail archive items appear in email search interfaces (see Creating a Mail Archive Mapping File).
Ensure the File connector runs in a 32-bit process.
On a 64-bit server, the File connector must run in a 32-bit process to be able to index PST mail archives. This is the default configuration because the connector uses a third-party library that does not support 64-bit processes. The parameter for the connector process type (32-bit or 64-bit) affects all sources for this connector. Consequently, you must ensure that the File connector runs in a 32-bit process (see Selecting a 32-bit or 64-bit Process for a Connector).
