# System Requirements

Exchange Web Service Connector can be installed as part of a larger system that includes an IDOL Server and an interface for the information stored in IDOL Server. To maximize performance, Micro Focus recommends that you install IDOL Server and the connector on different machines.

For information about the minimum system requirements required to run IDOL components, including Exchange Web Service Connector, refer to the IDOL Getting Started Guide.

Additional requirements for Exchange Web Service Connector are:

- Microsoft .NET Framework, version 4.5.

- Exchange Web Services Managed API 2.0 DLL. (This is installed automatically with the connector).

## IDOL Content

The Exchange Web Service Connector produces documents where the document reference (`DREREFERENCE`) is case-sensitive. Micro Focus recommends that you set `NormalizeReferences=FALSE` in the `[Server]` section of your IDOL Content component configuration file. Otherwise, if the connector produces documents with the same reference (in different case), IDOL Content de-deduplicates the documents.

## OmniGroupServer

To use Mapped Security for documents extracted from Exchange, you must extract LDAP security group information from Active Directory. You can do this using OmniGroupServer.
