# Viewing Field Mapping

Field mapping defines **which Exchange field corresponds to which vtenext field**.

For example, the main Exchange e-mail field can be mapped to the vtenext Contact e-mail field, the business phone to the company phone field, and so on.

## Where to find it

Open **Settings > Exchange Field Mapping**.

The page allows you to select a module and displays, for each row, the Exchange field and the associated vtenext field.

## Available modules

Mappings are available for Contacts, Organizations, Calendar / Events and Tasks. In the normal 24.08 interface, custom editing is available for **Contacts** and **Organizations**; Calendar and Task mappings are visible but are not edited with the same button.

## Locked fields

Some rows are mandatory or structural and are shown as **locked**. These fields cannot be changed from the mapping page.

## Before making changes

1. Take a screenshot of the current mapping.
2. Check whether the module is already used by many users.
3. Identify which fields are actually required.
4. Read [What Happens When a Mapping Is Changed](https://manual.vtenext.ch/books/exchange-connector-vtenext-Hfx/page/what-happens-when-a-mapping-is-changed).

A mapping change is not only a visual configuration change: it can trigger a new synchronization of existing records.
