Microsoft Exchange on Premise

You can connect to Exchange 2007, 2010, 2013, and 2016 on premise.

To create a new Microsoft Exchange data source, fill these fields.

Choose what you want to crawl

You can crawl:

  • the mailbox for an individual user

  • a set of mailboxes belonging to a set of users returned by an LDAP query

If you decide to use LDAP you might need to work with your network administrator or Exchange server administrator.

You can:

  1. Set up your LDAP query start point

  2. Set up your LDAP query filter

Configuring LDAP

You can specify the LDAP parameters that you want to use in a settings file. This is optional.

If you decide to use the settings file:

  • the parameters you specify in the settings file become the defaults every time you create a new Exchange on Premise data source.

  • at that time, you can accept them or override them.

  • our Support team will help you.

If you decide not to use the settings file:

  • you’ll need to set your LDAP parameters each time you define a new Exchange on Premise data source.

  • your network admin or Exchange admin should be able to help.

Create the data source in NOW Privacy

  1. From the main menu select Data Sources

  2. Click NewNew Data Source

  3. In the New Data Source dialog, select the dataset this new data source will belong to by:

    1. choosing an existing dataset from the dropdown, or

    2. clicking Add to new Data Set and typing the name of your dataset

      If you use option 3b, remember to add the dataset to at least one security group. If you don’t, no users will be able to see the data from this data source.

  4. Click Next

  5. Select the data source and click Next

  6. Enter the credentials and details for the data source and click Next

Common fields:



Exchange User

A user who has read access to the data you want to crawl and the ability to read mailboxes using Microsoft Identity Impersonation †. The Exchange User must have a valid mailbox.

Exchange Password

Password for the Exchange user.


If you specify mailbox, NOW Privacy crawls just that mailbox. If you specify LDAP query, NOW Privacy crawls all the mailboxes that match the results of the query.

† Therefore, we only support objects that are accessible through impersonation.

Fields when the target is a mailbox:



Exchange Protocol


Exchange Server

The IP address or fully qualified domain name of the target Exchange server.


Specify one mailbox to crawl. For example:

Fields when the target is defined by an LDAP query:

  1. Select the country for this data source and click Next

    The country is used in geographical visualisations

  2. Optionally, click Add Custom Description

    This allows you to use you own description for this data source, rather than accept the default description that NOW Privacy provides

  3. Set the Crawl priority

  4. Specify whether you want to crawl once or continuously

  5. Click Start Crawl Immediately if you want to crawl the data right now

    Or you can start a crawl manually anytime you want

  6. Click Create Data Source


  1. Earlier versions of Exchange can have technical problems when the load is very high. If you experience problems, reduce the crawl priority to 40%.

  2. For posts in conversations, we do not extract:

  • the subject

  • the attachments

  1. We do not extract:

  • journal items in the Journal folder

  • notes in the notes folder and sub folder

  • tasks in the tasks folder and sub folder

  • contact Message Class items in the Contacts folder

  • attachments from the Calendar

This is due to technical restrictions.

  1. If you change a mailbox’s primary email address and then re-crawl the Exchange server, NOW Privacy sees it as a new mailbox. Any data that you previously crawled will be removed from NOW Privacy (along with all items’ associated tags).

    To re-crawl the mailbox next time you run a crawl, remember that the new mailbox name must still be covered by the LDAP query. If the new name is no longer matched by the LDAP query, NOW Privacy ignores the mailbox.
